基于水平薄弱层破坏准则的密肋复合墙受剪承载力计算
|
摘要
针对密肋复合墙的特殊构造形式与破坏特点,提出了以水平薄弱层为分割面推导墙体受剪承载力的水平薄弱层破坏准则概念,并对其破坏机理进行了分析。以水平薄弱层破坏准则为基础,结合约束状态下填充砌块试件的荷载试验,采用理论与经验相结合的方法建立了密肋复合墙受剪承载力计算式,并利用不同框格数量密肋复合墙模型试验数据进行了验证,完善了墙体受剪承载力计算方法。研究表明:密肋复合墙的肋梁受剪作用及所受竖向荷载作用由计算式中肋柱受剪承载力、框格约束效应影响系数及压剪复合受力影响系数予以反映,其计算原理更加符合该类墙体的实际受力特点与破坏特征;依据水平薄弱层破坏准则建立的密肋复合墙受剪承载力计算式,物理意义明确,计算过程简便,满足一般工程精度要求。
According to the characteristics of the structural details and failure mode of the multi-grid composite walls,horizontal weak layer failure criteria for deriving the expression of shear load-bearing capacity of the walls was proposed in this paper.The mechanism and characteristics of the failure criteria were investigated.Based on the horizontal weak layer failure criteria,and combined with experimental research on filling blocks under restraint,the formula for calculating the shear load-bearing capacity of the multi-grid composite walls was proposed,which was verified by experiments of multi-grid composite wall specimens.The shear load-bearing capacity calculation method for the wall was improved.Shear effect of the grid beam and vertical load to the wall were considered by the shear load-bearing capacity of the grid column,influence coefficient of grid constraint effect and influence coefficient of combined force,which is in accordance with the actual force and damage characteristics of the wall.The formula proposed in this paper is accurate and simple,and can be meet the accuracy requirement for general engineering.
