Optimum Seismic Design of Steel Moment Resisiting Frames Using Time History Analysis


Abstract eng:
This paper presents the application of an innovative approach for performance-based design of structures. This approach is does not require a standard pattern for the distribution of seismic loads, and instead it is based on the principle of gradual adaptation of structural members to the seismic demand. The approach has already been implemented successfully for seismic design of various structural systems, and it has been shown that in most cases an optimum design can be reached accompanied by a uniform distribution of plastic deformations. The paper specifically discusses the application of the adaptation approach for the steel moment resisting frames (MRF). Five and ten storey MRF models are subjected to several seismic records. The reference model is designed in accordance with the seismic load pattern given in ASCE07-10. Other models are completely free to choose any distribution material to arrive at an optimal performance. The result is promising. It is demonstrated that the application of adaptation approach leads to a remarkable reduction in the weight of the structure at a given performance target. Alternatively, it can result in a considerable improvement of the performance, for a given structural weight.
