【摘要】 就2011砌体结构规范第5.5.1条和第8.2.8条提出了进一步完善的修订建议.其中就第5.5.1条关于砌体受剪构件计算公式如何反映不同块材砌体类别带来的抗剪性能与承载力的变化,提出了"砌体类别修正系数",以保证公式的统一模式和可靠性.新增补的第8.2.8条第1款的内力计算方法,未能充分反映带构造柱组合砖墙的受力特点,所采用的第4.2.5条关于计算简图和偏心弯矩的计算方法与组合墙的结构性能不符,通过大量试验研究和理论分析,提出了采用"组合框架"力学模型进行内力分析建议,并对其第2款关于组合墙截面计算方法作了切合实际的补充与界定.通过修订,将使带构造柱组合墙的设计方法趋于完善、合理,对扩大组合墙(特别在地震区)的应用,无疑具有重要的现实意义.更多还原

【Abstract】 This study was conducted to propose some revising suggestions in article 5.5.1and 8.2.8of the current Design Code of Masonry Structure(2011).For article 5.5.1,we put forward the "class of masonry correction coefficient",to ensure the unity and reliability of the formula of shear member of masonry,which reflected the variation of shear behavior and bearing capacity for different material masonries.The internal force calculation method in new additions of paragraph 1of article 8.2.8is not sufficient reflecting the stress of the brick wall with constructional column group characteristics.It adopted the method of calculating diagram and eccentric bending moment in article 4.2.5result that was not in conformity with the composite wall structure performance.Through a large number of experimental study and theoretical analysis,the"composite frame"mechanical model is adopted to improve the internal force analysis;and the practical supplement and definition are made for paragraph 2of article 8.2.8about composite wall section calculation method.By revision,the wall with constructional column group characteristics design method is perfected and rationalized,so as to expand the application range(especially in the earthquake region);it has important practical significance.更多还原
