Analysis On Seismic Performance Of Recycled Concrete Multi-ribbed Composite Wall

The recycled concrete multi-ribbed composite wall is further exploration based on ordinary multi-ribbed composite wall. It not only embodies originally characteristics of natural multi-ribbed composite wall, including ecological,energy-saving and good aseismic performance ,but also lots of recycled aggregate are used in the multi-ribbed composite wall that could disposed of lots of construction waste and achieve the objective of material recycling.However, depth analysis on seismic performance of recycled concrete multi-ribbed composite wall is very important in engineering application of recycled concrete multi-ribbed composite wall. Recycled concrete multi-ribbed composite wall of different recycled aggregate is studied by seismic experient in this paper. The main research contents are described as follows:(1)By the experiment and analysis of two recycled concrete multi-ribbed walls (composed of 100%,50% recycled aggregate) under horizontal loads, the result is showed that the failure pattern is shearing failure and there is no difference compared with natural multi-ribbed composite wall,including elastic stage, elastic-plastic stage and failue stage.(2) The nonlinear FEM is employed to the recycled concrete ulti-ribbed composite wall.lt makes us have further understanding about the seismic performance of recycled concrete multi-ribbed composite wall,and the result of nonlinear FEM analysis is compared with the experimental result. This paper also makes further discussion about the oblique section bearing capacity based on previous researchs.(3) Based on the experimental results and previous researchs,this paper establishs the damage model of the recycled concrete multi-ribbed composite wall and some parameters .And the seismic design method based on damage is putted forward in this paper.
