COMPARISON OF FORCE-BASED SEISMIC DESIGN METHOD WITH DISPLACEMENT-BASED SEISMIC DESIGN METHOD

A 8-story reinforced concrete frame structure is designed by using the force-based seismic design method.Then, the performance of frame structure is divided into three levels: serviceability, life-safety, and collapse protection. The three levels are quantified with story drift ratios, base shear and top displacement of the structure is calculated for three performance levels. For serviceability and collapse protection, the members is proportioned and the appropriate reinforcement selected, and details of seismic design is taken to ensure the deformability of the structure. The calculation results are verified by non-linear static analysis method. The results of two design methods are compared. Analysis result shows the members section reinforcements based on serviceability performance level are close to those by the force-based seismic design.
