MECHANICAL PERFORMANCE OF COMBINATION OF LONG SPAN STEEL SUPPORT OF FISH-BELLIED BEAMS AND CONCRETE SUPPORT
This paper studies the reliability of steel-concrete composite system through a practical project in Kun-shan,in which the composite scheme of long span steel support of fish-bellied beams and concrete support and the whole concrete support scheme are compared.By integral modeling and monitoring data analyzing,it is proved that the combined form of steel support of fish bellied beams and concrete support is more effective in controlling the de-formation of foundation pit.It shows that the combined form of steel support of fish-belly beams and concrete sup-port is reliable and has broad application prospect in engineering practice.
