Abstract: Earthquakes are natural disasters that cause a significant loss of life and property. Chiang Mai is located in the north, with many earthquake faults indicating that Chiang Mai is at risk of an earthquake. This study demonstrates the importance of seismic performance base design of precast concrete buildings (PC). The 10-story apartment precast concrete building be modeled locate in Chiang Mai. The building is designed as per Department of Public Works and Town & Country Planning DPT1302-18. Buildings will be evaluated for earthquake resistance performance using nonlinear time history analysis, which uses the acceleration of the earthquake recorded from earthquakes of 7 waves. The acceleration of the earthquake will be matched to the design spectrum using ETABS software. Identify the plastic hinge properties of shear walls and moment curvature by using the stress strain model for concrete and steel as specified in Department of Public Works and Town & Country Planning DPT.1303-14. The results of analysis by the linear static analysis be designed and evaluated by the nonlinear static analysis and the nonlinear dynamic analysis. Including the analysis results from all 3 methods to compare the displacement of buildings, Base shear and Story drift.
