Abstract

Abstract

According to three sites measurement to axial force of vertical strut of superhigh or large-span form strut system, the influences on internal force of vertical strut by different pouring methods of concrete and structure type of floor system were analyzed. The results showed that pouring method and floor system had significant effect on high or large-span form strut axial force. Compared to manual pouring, pumping had not only horizontal impact force but also vertical impact force. Compared to flat roof, the axial force of vertical strut in sloping roof form strut system was more uneven and the maximal difference reached about 2 times. According to the measured results, the present formula should be revised and corresponding research methods were put forward. In the end, the finite element simulation was done by ABAQUS.
