| Summary, etc. |
Due to its location in the Pacific Ring of Fire, the Philippines has always anticipated<br/>potential destructive earthquakes that could severely damage important structures like<br/>schools. The City of Manila is highly susceptible to liquefaction, making any structures<br/>built on its soil vulnerable to liquefaction-induced settlement brought on by earthquake<br/>loads. This study employs to analyze and showcase the variance in settlement of the<br/><br/>underlying soil and foundation of a low-rise school structure in the highly liquefaction-<br/>prone soil of Manila under various earthquake loads. It does this by using the FEM<br/><br/>software, PLAXIS 3D. The methodology is divided into two distinct categories: empirical<br/>analysis using manual calculation and numerical analysis using software. By considering<br/>the foundation weight, structural loads, and all three loads—including the various<br/>earthquake loads—the FEM analysis is used to calculate the settlement of soil and<br/>foundation. The empirical analysis is used for the settlement using the three loads used in<br/>PLAXIS 3D and the differential settlement and angular rotation, which was used to<br/>evaluate the stability of the structure using Preene's stability criteria. In the evaluation using<br/>Preene's stability criteria, the angular rotation of 1/300 and differential settlement of less<br/>than 2 cm falls only under the slight risk criteria, which implies that the damage in the<br/>building will only be limited to cracks of 1 mm in maximum width and no significant<br/>structural damage. The PLAXIS 3D results show that the foundation's self-weight<br/>settlement is 5.472 mm and that the maximum total displacement in the foundation results<br/>from the structure's gradual consolidation over time—is 22.25 mm when the point load<br/>from the structure's dead load is applied. The different earthquake loads were added using<br/>the same model of the soil foundation and structure under the point load from the structure's<br/><br/>vi<br/>dead load and the extracted time and acceleration data in cm/sec2 from the SeismoSignal<br/>time-acceleration input of the earthquake event data. The maximum total displacement<br/>along the foundation due to earthquake data with magnitudes of 5.1, 6.5, and 7.0 is 22.28<br/>mm, 22.37 mm, and 22.38 mm, respectively. In comparison to the empirical analysis using<br/>manual computation, show the differential settlments for the magnitudes 5.1, 6.5, and 7.0<br/>earthquakes to be differential settlement of 21.170 mm, 21.186 mm, and 21.287<br/>respectively. The angular rotation based on the manual computation using differential<br/>settlement is 8.019x10-4, 8.025x10-4, and 8.063x10-4 listed respectively for the three<br/>earthquake magnitudes mentioned above. The findings, derived from both empirical<br/>analysis and the Finite Element Method, showed that the settlement values as well as<br/>angular distortions do not exceed 1/500, which, following Preene's (2000) building damage<br/>criteria, falls into the slight risk category which suggests the possibility of superficial<br/>damage with no significant effect to the structural integrity of the building. |
