摘要(Abstract):

对11根T形、6根L形及2根矩形截面钢筋砼双向压弯构件进行了试验研究,在此基础上用电算程序进行理论计算,结果与试验结果吻合较好。同时还根据大量电算分析揭示了T形、L形截面双向压弯构件正截面承载力的变化规律。最后,编写了用于配筋计算的电算程序,该程序亦适用于其它任意截面形状压弯构件的正截面承载力计算。
An experimental research on R. C. members of 11 T-shaped, 6 L-shaped and 2 rectangular section under axial compression and biaxial bending is achieved. On the basis of the experimental results, a computer program is compiled, and the theoretical calculation is conducted. The calculational result coincides with the experimental result well. Simultaneously, the variation regularity of bearing capacity of T, L-shaped columns, subjected to axial compression and biaxial bending is obtained. Finally, a computer program for the calculation of column reinforcement is compiled. It can also be used for the calculation of element bearing capacity with arbitrary shaped cross-section subjected to axial compression and biaxial bending.
