| Summary: | <p align="justify">This research is a development from several methods and experiments In which the behavior of dynamic pressure against the basement wall is analyzed. In this research, the certain consideration is the effect of inertia of upper structure, basement, and the bored pile foundation <br />
<br />
The objective of the analysis is to evaluate lateral earth presure due to the dynamic load against the basement wall and the inertial force of the upper structure applied to the basement structure and the foundation due to a 2500-years-return-period-earthquake, as a case study is 48 m width basement, the depth varies from 3 to 7 basements, and a 30-stories high building which reaches 126 meters. <br />
<br />
Analysis of lateral earth pressure of basement and pile foundation is done numerically using the finite element method software PLAXIS Dynamic 2D. The results of the analysis are then compared with previous researches such as Mononobe-Okabe (1929), Wood (1975), Sitar and Wagner (2016), also Izumi and Miura (2004). <br />
<br />
Based on the results of the analysis, the seismic lateral earth pressure has a non-linear increase and decrease, depends on the soild depth (triangular distribution), similar as the research conducted by Mononobe-Okabe (1929) and Wood (1975), as it increases at a certain depth then decreases at a certain depth, which also consistent with the Sitar and Wagner (2016) study, using the FLAC program. The increase of seismic coefficient value of the basement wall is also similar to Sitar and Wagner’s research (2016). While the seismic coefficient of pile foundation (k) has a similar value to the results of numerical analysis of Izumi and Miura (2004).<p align="justify"> |
