众所周知,钢管砼结构是把上部荷载的轴向力传递到钢管和砼上,而超级砼结构是在钢管的内表面涂抹分离材料,他砼与钢管不粘结在一起,只有砼部分传递轴向力(见图),钢管在砼的周围起到约束砼的作用。利用这种约束效果,可以得到很大的轴向承载力。钢管不仅能够承受圆周方向的应力,同时还能承受弯矩,因此,在结构上,它比钢管砼具有更大的优越性。根据试验结果证明,超级砼结构的最大优点是,当构件达到最大的轴向承载力之后,即使构件
As we all know, the steel pipe concrete structure transmits the axial force of the upper load to the steel pipe and the concrete, while the super concrete structure applies the separating material on the inner surface of the steel pipe. The concrete is not bonded to the steel pipe and only the concrete part transfers the axial direction. Force (see figure), the steel pipe plays a role in confining the ripple around the concrete. With this constraining effect, a large axial bearing capacity can be obtained. The steel pipe can not only withstand the stress in the circumferential direction, but also can withstand the bending moment. Therefore, in the structure, it has greater advantages than the steel pipe concrete. According to the test results, the biggest advantage of the super crucible structure is that, after the component reaches the maximum axial load capacity,
