Effect from Brick Wall Strength on Response of Reinforced Concrete Structure under Earthquake

Abstract

This research aimed to investigate responses of reinforced concrete structures which considered brick wall with main structures under an earthquake. Owing to, generally the brick wall has not taken in the analysis, for this research, the comparison of the structural responses between the main structures with and without brick wall were conducted. 3-and 10-story RC building, designed following DPT. 1301-54 code, were selected as case studies and were analyzed under nonlinear static analysis (Pushover analysis) process. The response spectrum from B.E. 2550 ministerial regulations is used as lateral seismic forces. The analytical results found that the brick wall strength effects shear forces and bending moment in columns increased through heights importantly. Therefore, brick wall strength should be considered in structural design.
