Displacement Based Seismic Design

According to lots of documents previously studied, a seismic design method is put forward based on displacement for steel moment frame. This method is established in condition that the yield displacement of steel frame can be determined by its geometrical dimension; then the objective displacement (ultimate displacement) can be determined in light of performance level of the structure, and the corresponding coefficient of ductility can be obtained. Thereafter, the design base shear of steel frame structure can be calculated by the use of reduced elastic spectrum. Thus, the design of stiffness and capacity can be conducted on steel frame structure. The analysis of case study indicates that the displacement-based seismic design method addressed herein is of reasonable safety and reliability, and of operational convenience, which can still realize the seismic design of steel frame structure at different performance levels.

Displacement Based Seismic Design

AbstractFor performance-based seismic engineering of buildings, the direct displacement-based seismic design method is different from the coefficient method used in FEMA-273 and the capacity spectrum method adopted in ATC-40. The method not only is a linear static procedure but also is applied to the design of new constructions. This paper concerns with experimental studies on the accuracy of the direct displacement-based design procedure. Experimental results of three reinforced concrete (RC) columns designed by the displacement procedure are presented and discussed through pseudo-dynamic tests and cyclic loading tests. From the tests, it is shown that the stiffness degrading factor of RC columns plays a key role. The direct displacement-based seismic design method can reliably capture the maximum displacement demand of the test RC columns if the stiffness degrading factor adopted in the displacement design method for RC material is adequate.

Displacement Based Seismic Design

Displacement based seismic design of RC frame with friction damper is proposed in this paper based on the displacement shape of RC frame. and multi-degree-of-freedom system is transformed into an effective single-degree-of-freedom system. Based on equivalent linearization equivalent period is determined by using the elasto-plastic displacement response spectra, and then the structural members are designed. At the same time, target deformability of the frame and friction damper device is obtained by decomposing the structural storey drift. And the expected deformability of the structure can be guaranteed by appropriate the friction energy dissipation brace. This method could effectively control the seismic performance of the structure in earthquakes.
