【摘要】 对9榀不同形式的墙板进行了伪静力试验,介绍了墙板的破坏过程,分析了墙板的受力特点及影响墙板刚度及承载力的主要因素。结合试验及构造分析,按照混凝土体积不变的原则将墙板等效为正交各向异性的纤维加强复合材料,提出墙板弹性刚度计算公式;在弹塑性阶段分析了墙体承载力的组成,并以刚架斜压杆为计算模型,采用理论与经验相结合建立墙板抗剪承载力计算公式。计算值与试验值吻合较好,为密肋复合墙体结构设计提供了理论依据。更多还原

【Abstract】 Based on the pseudo static tests of 9 pieces multi-ribbed composite walls,the failure processes and mechanical behaviors of the walls were studied,and main factors that affect the lateral rigidity and shear resisting capacity were analyzed.The paper equaled the prototype wall to wall made of orthotropic fiber reinforced composite according to the rule that the concrete section area remains the same based on analyses of the constitution and experiments,and formula of lateral rigidity of the wall was advised.Composition of shear resisting capacity was discussed in elastic-plastic stage,and formula for shear capacity was proposed based on theoretical analysis and test results according to rigid frame diagonal strut model,which provide theoretical foundation for the design of the multi-ribbed composite wall structure.更多还原
