提出了基于开裂薄膜理论(Cracked Membrane Model)的程序化斜裂缝计算方法,并利用此方法对有限元分析得到的单元应力场进行计算,从而得到墙体斜裂缝的宽度、间距和倾角,并与法国国家科研项目CEOS.FR框架下进行的钢筋混凝土剪力墙受剪试验得到的结果进行了对比。计算时,分别采用三个不同规范的裂缝间距计算公式和开裂薄膜理论推导公式进行对比分析,进而得出这些公式在计算墙体斜裂缝时的差异与准确性。
The calculation method of programmed oblique crack based on Cracked Membrane Model is put forward and the stress field of the element obtained by finite element analysis is calculated by this method to get the width, The result of shear test of reinforced concrete shear wall under the framework of CEOS.FR, a national research project of France, is contrasted. In the calculation, the calculation formulas of the crack spacing and the theoretical formulas of the cracked film were compared and analyzed respectively by using three different specifications, and then the differences and the accuracy of these formulas in calculating the oblique crack of the wall were obtained.
