Article title: Evaluation of interpretation criteria for drilled shafts with tip post-grouting
Authors: Yit-Jin Chen, Wei-Yi Lin, Anjerick Topacio, Kok-Kwang Phoon
Publication title: Soils and Foundations -Tokyo- 61(6), September 2021
Abstract:
This paper evaluates the effects of tip post-grouting on various capacity interpretation criteria for drilled shafts under compression loading. A wide array of load test data for drilled shafts constructed using three post-grouting methods, including tube-a-Manchette, flat jack, and jet grouting, is utilized for the analysis. The load tests were divided based on the different tip post-grouting methods, then they were further divided based on the soil conditions (undrained or drained). The interpreted capacity and displacement at the interpreted capacity are examined for each interpretation criterion. Furthermore, the interpreted results were compared with current studies on drilled shafts that are not subjected to tip post-grouting techniques to determine the effects of post-grouting methods. Based on these analyses, the normalized load–displacement curves and the relationships between various interpretation criteria for drilled shafts with tip post-grouting are established. The drilled shafts subjected to any post-grouting method produced higher capacity and yield larger displacement with the same amount of normalized capacities for undrained and drained soils compared to drilled shafts not subjected to any post grouting procedures. Among the three grouting methods studied, the jet grouting method can produce a greater capacity than the other methods, especially for drained soil conditions. Finally, specific recommendations to guide the design of drilled shafts with tip post-grouting are provided.

Article title: Evaluation of side resistance for drilled shafts in rock sections
Authors: Anjerick Topacio
Publication title: Geomechanics and Engineering 21(6):503-511, June 2020
Abstract:
This study evaluated the side resistance of drilled shafts socketed into rock sections. Commonly used analysis methods for side resistance of piles in rocks are examined by utilizing a large number of load test data. The analysis of the unit side resistance of pile foundations embedded into rock sections is based on an empirical coefficient (α) and the uniaxial compressive strength (qu) or its root (√qu). The Davisson criterion was used to interpret the resistance capacity from the load test results to acquire the computed relationships. The α-√qu relationship is proven to be reliable in the prediction of friction resistance. This study further analyzed the relationship by including the effect of rock quality designation (RQD) on the results. Analysis results showed that the analysis model of α-√qu-RQD provided better prediction and reliability considering the RQD classification. Based on these analyses, the side resistance of drilled shafts socked into rocks is provided with statistical data to support the analysis.

Article title: Side Resistance of Drilled Shafts Socketed into Rocks for Serviceability and Ultimate Limit States
Authors: Yit-Jin Chen, Cheng-Chieh Hsiao, Anjerick Topacio
Publication title: Advances in Technology Innovation 5(3), March 2020
Abstract:
This study evaluates the analysis models of side resistance in rock sections by utilizing a wide variety of load test data. Available analytical models including the empirical adhesion factor versus the rock’s uniaxial compressive strength and its root are analyzed and compared statistically to determine the optimum relationships. The interpretation criteria for the L1 and L2 methods are used to analyze the load test results for serviceability and ultimate limit states, respectively. The analysis results show that the relationship model with the empirical adhesion factor versus the root of the rock’s uniaxial compressive strength exhibits better correlation than the one with the rock’s uniaxial compressive strength. Moreover, the general coordinate axes regression equation demonstrates better reliability than the semi-logarithmic and full logarithmic axes equations for both limit states. Based on these analyses, specific design recommendations for the side resistance of drilled shafts socketed into rocks are developed and provided with the appropriate statistics to verify their reliability.

Article title: Soil Bearing Capacity Reference for Dasmariñas City, Philippines
Authors: Engr. Anjerick Topacio, M. Eng, Danna Mae J. Garduce, Gregorio S. Magoncia III, and Maricris S. Marcelo
Publication title: N/A
Abstract:
Soil is one of the oldest and most complex component when it comes to structural design. One of the basic requirements for designing a specific structure is estimating the capability of the soil to withstand a specific amount of load. The standard penetration test is one of the existing methods used in estimating the soil bearing capacity of a certain locale. But due to economic limitations, not all low-rise structures are willing to consider conducting this type of test. The purpose of this study is to analyze the soil bearing capacity of the different barangays and to develop a soil bearing capacity reference for Dasmariñas City, Philippines. The allowable bearing capacity to be used for contouring the soil bearing capacity map are calculated through various theories and studies using geotechnical parameters like cohesion and angle of friction of soil that are correlated to the Standard Penetration Test (SPT).

Article title: Experimental Investigation on the Reduction of Common Air Pollutants from Vehicle Emission Using Concrete Bricks with Titanium Dioxide
Authors: Anjerick J. Topacio , Trifonio C. Balbin III , Shaina Barsana , and Cheska Nicole C. Ravelo
Publication title: International Journal for Computational Civil and Structural Engineering 7(2), May 2018
Abstract:
On a global scale, air pollution is considered to be one of the leading environmental problems. Energy consumption, fuel burnings, industrial processes, mobile and agricultural sources, and emissions continue to worsen our current air condition. With the knowledge that titanium dioxide can decompose harmful gases through the process called photocatalysis (discovered by Akira Fujishima in 1972), an investigation regarding its use on concrete bricks to reduce common air pollutants from vehicular emission is pursued by the researchers. Through the process of experimentation, the study aims to know the percentage reduction on the following parameters: carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2) and lead (Pb) as well as to know if titanium dioxide will have a negative effect when used with concrete. The tests used in accordance to the objective of the study were air test, which is conducted by First Analytical Services and Technical Cooperatives (F.A.S.T laboratories). After the analysis, the data were recorded and tabulated. Graphs were presented to show the differences in percentage reductions. Results of air test showed relative reduction on air pollutants, an average reduction of 77.38 percent on carbon monoxide, 40.48 percent on nitrogen dioxide and 81.43 percent on sulfur dioxide. However, the reduction on lead was not identified. The Researchers conclude that concrete bricks with titanium dioxide will be able to help reduce air pollution especially on urbanized areas experiencing high vehicular emissions.

Article title: Development of Hydrophobic Composite Roof Tiles Utilizing Recycled Plastic Materials
Authors: Anjerick Topacio, M.Eng, Rochelle C. Arkuino, Katherine V. Romano, and Jayvee C. Abutin
Publication title: N/A
Abstract:
The study investigates the most optimal mix ratio of the roof tile constituents to achieve the desirable engineering properties of light weight, strength, and water tightness. Plastics are non-biodegradable materials, so nature cannot absorb them as other waste. The purpose of this research work was to provide an alternative to other traditional building technologies that consume non-renewable resources, or produce negative environmental impact. It also paved the way for the utilization of Expanded Polystyrene plastic as substitute for concrete in developing roof tiles that will meet the ASTM requirements in order to help contribute to the industry in saving the environment, to encourage the government to find solutions regarding the disposal to landfills of solid waste materials, to provide new knowledge to the contractors and developers on how to improve the construction industry methods and services by using recycled plastic material, and to sustain good product performance and meet recycling goals.

Article title: Comparative Study of Potential Liquefaction of Three Selected Locations along the Pasig City Segment of the Valley Fault System, Philippines
Authors: Anjerick J. Topacio, Alyssa Erika P. Ramos, Jayson E. Villaester, Joanna Carla A. Pacamparra
Publication title: Journal of Civil and Structural Engineering 4(1):55-69, April 2016
Abstract:
This study deals with the analysis of the potential seismic-induced liquefaction which is a complex ground failure phenomenon observed when saturated loose sand deposits loss its shear strength. It may be quantified as to the damage that it causes to the built infrastructures within the vicinity. This study was conducted to determine the potential liquefaction of three specific locations along the Pasig City segment of the Valley Fault System in Barangay Kapitolyo, Manggahan and Ugong and correlate it with their respective soil suitability. The study employed secondary data from geotechnical firms, DOST-PHIVOLCS and the local government unit of Pasig City. The results were assessed through the use of an excel program devised by the researchers based on a simplified procedure by Seed and Idriss (1997), and Das (1995). The factor of safety due to liquefaction (FS) at specific soil conditions was computed using this program and proved that the chosen location in barangay Ugong is the most susceptible to liquefaction among the three chosen locations. The mitigation measures for the soil and/or the type of foundations to be applied was considered and pile foundations are recommended in the locations in baranggay Manggahan and Ugong. Shallow foundations are, on the other hand, safe in barangay Kapitolyo.

Article title: Use of Recycled Rubber Tire Crumbs for Waterproofing of Concrete
Authors: Anjerick J. Topacio, Nikko C. Gozo, Sydh Roeth V. Marquez, Rommel Victor M. Poblete, Harriet S. Ramos
Publication title: International Journal of Civil and Structural Engineering Research 3(2): 95-132, October 2015-March 2016
Abstract:
This study describes the use and testing of recycled rubber tire crumbs as alternative construction material with waterproofing ability that could serve as a better alternative to the existing waterproofing products. This research seeks the further use of rubber tire crumbs as a waterproofing agent in concrete structures to help improve the recycling of waste materials in accordance with the principle of sustainable development. The test procedures used in this research made use of experiments like water absorption test, sorptivity test, and water permeability test, utilizing different sieve sizes of rubber crumbs. The results of the tests for the waterproofing ability of the rubber concrete mixture using these test procedures were compared with some of the waterproofing products available in the market to determine if the rubber crumbs could be an alternative. The compressive strength for non-bearing structures (600 psi) of the rubber concrete mixture has also been maintained since previous experiments with rubber components proved that the compressive ability of the concrete drastically went down. It is hoped that this research can help future studies in generating innovations with the use of rubber crumbs in construction.
