Study on Uniaxial Compressive Stress-Strain Curve of Reactive Powder Concrete with Waste Brick Powder
摘要
Abstract
In order to further understand the compression performance of RPC with waste brick powder,the stress-strain curve of RPC with waste brick powder was investigated through experimental analysis combined with finite element simulation.The random steel fiber finite element model at mesoscopic level was developed using Ansys.The model coincided well with the test results.Furthermore,the influence of steel fiber volume content on the compression curve of RPC was analyzed by numerical simulation.With the increase of cement replacement rate,the peak stress decreases,while the peak strain and elastic modulus decrease slightly but the change is not significant.The addition of steel fiber increased the peak stress,peak strain and elastic modulus of RPC.And with the increase of steel fiber content,the peak stress increased,the elastic modulus increased to a certain extent,and the peak strain did not change significantly.关键词
