鉴于我国规范对异形截面柱或荷载面的冲切强度计算未作明确规定,根据所进行的柱截面为三种典型异形柱(十字形、T形和L形)板柱连接冲切特性试验成果,并结合文献试验资料以及国外规范的作法,提出了符合我国设计实践的非矩形截面柱的板柱冲切强度计算模式.同时根据大量试验资料提出了适用于不同柱型的冲切强度计算公式,该公式不仅形式简单,且同ACI318规范及我国GB50010-2002规范方法相比,与不同试验结果的符合度均较好.
In view of our country norms for punching shear strength of profiled column or load surface is not clearly defined, according to the column section for the three typical special-shaped column (cruciform, T-shaped and L-shaped) plate column connection punching characteristics test results , And combined with the literature test data as well as the practice of foreign norms, proposed in line with our design practice of non-rectangular cross-section column plate punching strength calculation mode at the same time based on a large number of experimental data for different column punching shear strength formula , The formula is not only simple, and with the ACI318 norms and our GB50010-2002 normative method, compared with different test results are better.
