Reinforced concrete buildings are typically braced with shear walls positioned around lift shafts and stairs. Vertical transfer of load from slab to walls leads to a concentration of shear stress in the slab at wall ends and corners, which needs to be considered in punching shear design. This issue is not addressed in EN 1992 (2004) and only partially addressed in fib Model Code 2010 leaving engineers to resort to their own judgment. Consequently, consideration of punching shear at wall corners can be overlooked entirely or not properly addressed through lack of knowledge. The paper addresses this issue by proposing a method for calculating the design shear stress at wall corners for use in conjunction with the Critical Shear Crack Theory. The method is initially validated against test results for slabs supported on elongated columns as well as numerical simulations. Subsequently, the method is extended to the punching design of a slab supported by a wall corner. The proposed analysis of the slab‐wall corner junction is validated against the predictions of nonlinear finite element analysis (NLFEA) employing 3‐D solid elements as well as the joint‐shell punching model (JSPM) previously developed by the authors.

墙角支撑RC平板的冲剪设计

钢筋混凝土建筑物通常用剪力墙支撑，这些剪力墙位于电梯井和楼梯周围。荷载从板到墙的垂直传递会导致板在墙的两端和拐角处集中剪切应力，这在冲剪设计中需要考虑。EN 1992（2004）中未解决此问题，fib中仅部分解决了此问题Model Code 2010使工程师可以诉诸自己的判断。因此，由于缺乏知识，在壁角处冲切剪切的考虑可能会被完全忽略或无法正确解决。本文通过提出一种计算壁拐角处的设计剪应力的方法，与临界剪切裂纹理论结合使用，解决了这一问题。该方法最初针对细长柱支撑的平板的测试结果以及数值模拟进行了验证。随后，该方法扩展到由墙角支撑的板的冲压设计。平板墙角交界处的拟议分析已针对使用3D实体元素的非线性有限元分析（NLFEA）以及作者先前开发的节间冲孔模型（JSPM）进行了验证。
