| Abstract |
In a performance based seismic design (PBD) of a high-rise apartment building, the exterior RC walls are designed as non-structural
members; severe cracks and damages could occur even from a small earthquake which is a cause for anxiety for residents. In this study,
vulnerable members to seismic load were classified and the occurrence of cracking in the exterior walls regarded as non-structural members
of high-rise apartments were investigated by a linear time history analysis. In the linear time history analysis, a small seismic load of the
operational performance level was used. A numerical analysis model was applied to the exterior walls and horizontal components regarded as
non-structural members. The analysis results showed that the non-planar walls and the non-structured walls were classified as vulnerable
members to seismic loads. Furthermore, the horizontal components located in the upper and lower parts of the large opening and the
connecting beams adjacent to the core walls were also classified as vulnerable members to seismic load. |
