摘要:

对新型轻质墙体材料的弹性模量、干收缩值等进行了实验测定,建立了混凝土单元无配筋、混凝土单元有配筋、混凝土单元与钢丝网单元联合作用的三种有限元模型,并根据这三种有限元模型,计算了多种干收缩值情况下的最大主应力和裂纹的最大开裂长度;分析了墙体开裂与荷载、材料性质、配筋率等的关系以及墙体开裂与压碎的原因,为此种新型墙体材料在实际工程的使用提供了依据.

Abstract:

The elastic modulus and dry shrinkage value of the new lightweight wall material were experimentally determined, and three finite element models were established, namely the concrete unit without reinforcement, the concrete unit with reinforcement, and the concrete unit and the steel wire mesh unit working together, and according to these three finite element models, the maximum principal stress and the maximum cracking length of crack under various dry shrinkage values were calculated. The relationship between wall cracking and load, material properties, reinforcement ratio, etc., as well as the reasons for wall cracking and crushing, are analyzed, which provides a basis for the use of this new wall material in actual engineering.
