000018307 520__ $$2eng$$aLow yield strength steel is often used to make various type of energy-consuming or seismic damping devices because of its strong energy dissipation performance. Multi-ribbed composite wall structure (MRCWS) is composed of prefabricated multi-ribbed composite wall slab, cast-in-suit concealed outer frame and cast-in-place or precast floorslab, being a kind of lightweight, energy saving and environmental protection structure. In this paper, according to the basic component and construct characteristic of the multi-ribbed composite wall structure as well as high energy dissipation performance of low yield strength steel, a new multi-ribbed composite wall with low yield strength steel is provided for seismic mitigation of the structure, while the low yield strength steel of 100MPa, 160MPa and 225MPa grade is chosen. The earthquake response analysis of the control structure systems under horizontal earthquake wave has been carried out by using program IDARC2D. The seismic mitigation effect of the low yield point steel panel for the multi-ribbed composite wall structure was discussed. The calculating results show that the low yield strength steel panels have obvious seismic reducing effect for the multi-ribbed composite wall structure, which seismic damping rate is 15%~30% under the seismic frequent intensity, and is 30%~60% under the seismic fortification intensity and the seismic rare intensity at 8 degree seismic fortification region of China Code for seismic design of buildings, so a simple and effective seismic mitigation technique is provided for the multi-ribbed composite wall structure.
