【摘要】 砌体本构关系的研究是砌体基本力学性能研究的重点之一,至今还没有建立起具有广泛适用性的砌体本构关系,通过对现有的弹性本构关系、经验本构关系和损伤本构关系进行综述,发展了较为前沿的砌体随机损伤本构关系概念和方法,并用试验结果加以验证,理论分析与试验结果吻合良好.更多还原

【Abstract】 The constitutive law of masonry is an important subject of the basic mechanical properties,especiallythe compressive stress-strain curve.It has a great value in theoretical research and engineering applications,but awidely used constitutive model has not been established until now.Elastic and experienced constitutive relations aresummarized and commented.The damage constitutive models include stochastic damage constitutive relation areintroduced and suggested.Compared with test results,it is found that the analytical results have a good agreementwith experiments’.更多还原
