对８根十字形截面钢筋砼构件在轴向力及双向弯矩共同作用下的反复加载试验研究，揭示了十字形截面钢筋砼双向压弯构件的破坏形态及正截面承载力的一般规律。在此基础上，采用数值迭代方法，编制了相应的电算程序，对其受力性能做了进一步的理论分析，提出了十字形截面钢筋砼双向压弯构件正截面承载力的计算方法。
The repeated loading test of eight cruciform reinforced concrete members under axial and biaxial bending moments reveals the failure modes of the cruciform reinforced concrete members and the general law of normal section bearing capacity. Based on this, a numerical iterative method was used to compile the corresponding computer program, and further theoretical analysis was made on its mechanical performance. A method for calculating the normal section bearing capacity of the bi-crucible reinforced concrete member with cruciform cross section was proposed.
