基于不同破坏准则的组合墙房屋抗震可靠性分析
Aseismic Reliability Analysis of RC Brick/Block Composite Masonry Buildings Based on Different Damage Criteria
【摘要】 介绍了最大位移-能量双重破坏准则,并以此准则和最大位移破坏准则用JC法计算了一幢八层钢筋混凝土-空心砖组合砌体房屋的可靠度。比较分析了两种破坏准则在钢筋混凝土-空心砖组合砌体结构可靠性分析中的差异。在对20道组合砌体墙片试验分析的基础上,分析了滞回包络线面积代表的能量和最大位移对结构破坏描述的差异,得出了对工程有意义的结论。
【Abstract】 A double damage criterion expressed in terms of maximum deformation and hysteresis energy is introduced.Ac- cording to this criterion and the maximum deformation criterion , the reliability of a 8-storey RC-brick composite masonry building is calculated by JC method.The two damage criteris,which are used in reliability analysis of RC-brick composite masonry system,are compared.Based on the test and analysis of 20 RC-brick composite ma- sonry walls, the relationship between the energy denoted by the area of hysteresis curve and the maximum defor- mation is studied.And a valuable conclusion is drawn.
【Key words】 damage criterion; hysteresis curve; RC-brick composite masonry structure; reliability analys?;
