| Summary: | 碩士 === 國立臺北科技大學 === 土木與防災研究所 === 98 === The seismic capacity of existing buildings fails to meet the new seismic code in Taiwan. To increase the seismic capacity, the most common solution for existing buildings is to build additional RC shear walls. However, opens on the shear wall are required for light and air. The searching or engineering get the information of the seismic capacity of the RC shear wall with opening by experiment which always spend a lot of money, time and person. In this thesis, we use the method Computer-Aided Engineering (CAE) to investigate the crack distribution and evolution by analysis the six specimens which include framed shear walls with opening, high-, low-rise, door, and window framed shear walls. In the finite element software, ANSYS, build the real size RC wall with the six specimens called numerical model, and use the 3-D solid element to simulate concrete and 3-D spear element to simulate steel rebar called element model, then use the plasticity theorem which included the multilinear isotropic hardening using Von-Mises plasticity and Willian-Warnke five-parameter model called material model. Based on the above three models, the finite element model was used to perform the nonlinear pushover analysis. It is similarity that compares the analytical results which includes the crack positions, distributions and evolutions with experimental result. In this thesis, the cracking distributions and the evolutions of RC wall with opening were simulated by finite element method and plasticity theorems, and these results can provide engineers or researchers the information of the crack distributions and evolutions of the RC wall with opening.
