摘要

本文对钢筋混凝土板在纯扭转作用下的力学性能进行了实验和数值研究。主要检测参数为:配筋率或间距、板宽。对9块不同尺寸和配筋的钢筋混凝土板进行了纯扭转试验。所有试件均采用有限元法和扭转理论进行三维数值分析。有限元计算结果高估了开裂力矩，极限力矩准确。与有限元等理论相比，斜弯理论计算的开裂力矩更为精确。此外，ac318 -14建筑规范对开裂扭矩不保守，对极限扭矩保守。

Torsional behavior of reinforced concrete plates under pure torsion

The present study investigated experimentally and numerically the behavior of reinforced concrete plates subjected to pure torsion. The main parameters examined were: steel reinforcement ratio or spacing and plate width. A pure torsion test was carried out on nine reinforced concrete plate with different dimensions and reinforcement. A 3D numerical analysis by the finite element method and a torsion theories were adopted for all specimens tested. The finite element results overestimate the cracking torque, accurate of ultimate torque. Skew-bending theory calculate the cracking torque more accurate compared to FE and other theories. Moreover, ACI318-14 building code is unconservative for cracking torque, conservative of ultimate torque.
