深基坑中混凝土内支撑自重对其轴力及变形的影响

Influence of Self-weight of Concrete Inner Brace on Axial Force and Deformation in Deep Foundation Pit

文中探讨了钢筋混凝土内支撑构件在其他荷载和作用保持不变的情况下,重力对其所产生轴向力与变形的影响,结果表明,当所受轴向压力较小时,钢筋混凝土内支撑内力与变形规律更接近于压弯构件,受重力影响产生的挠度会在较大程度上影响内支撑杆件的受力与变形性能。

This paper discusses the gravity effect on the relationship between the axial force and deformation of reinforced concrete internal support member under the condition that the other load and function remains unchanged. And the results show that the stress pattern of internal support member tend to the bending member when its axial stress is small. And the deflection caused by the self-weight has a larger impact on the performance of internal support.
