STUDY ON NON-LINEAR EARTHQUAKE RESPONSE OF MULTI-RIBBED COMPOSITE SLAB STRUCTURE WITH THE MICRO-ANALYSIS MODEL

摘要

Earthquakes pose one of the greatest challenges to the designers of buildings and other civil engineering structures. The multi-ribbed composite slab structure as one of new residential structures has been built at some regions in China, and researchers need to investigate their seismic behaviour features. The multi-ribbed composite slab structure is constructed with multi-ribbed composite walls and latent frames. The micro-analysis FEM model of the multi-ribbed composite slab structure is built up by beam elements and shell elements. Three- dimension computational model was adopted in the non- linear time history earthquake response of 1/10 model in shaking table test and its earthquake response was given. The calculated curves agree well with the experimental ones. The analysis shows that the micro- analysis FEM model and non-linear time history method can be use in aseismic safety evaluation of the multi-ribbed composite slab structure.
