摘要
依据12个钢纤维混凝土简支墙梁试件的试验情况,研究了钢纤维混凝土简支墙梁开裂荷载、破坏荷载、裂缝和挠度的特点.确定了钢纤维的最佳掺量.运用力学的基本原理,建立了钢纤维混凝土简支墙梁的计算模型,提出了有限元分析钢纤维混凝土简支墙梁性能的方法.通过算例,验证了有限元分析钢纤维混凝土简支墙梁受力性能的方法的正确性.
According to the test results of 12 specimens of steel fiber concrete simply supported Wall-beam,the properties were studied,that the cracking load,failure load,crack and deflection the limit bearing capacity of steel fiber concrete simply supported wall-beam.Optimum content of steel fiber was determined.The calculating model of steel fiber concrete simply supported wall-beam was founded by using the principle fundamentals of mechanics.The method was taken that of steel fiber concrete simply supported wall-beam tube that analyzed with nonlinear finite element.It is shown that the finite element analyzed the mechanical properties of steel fiber concrete simply supported Wall-beam.
