The influence of fastener-style steel pipe falsework's configurations on bearing capacity

Based on FEM,the influence of configurations of fastener-style steel pipe falsework's on bearing capacity is discussed on this paper.It is found:the distance and step length of upright bars,the crossing brace in upright planes,the sweeping staff are all sensitive elements to bearing capacity of falsework.But the cross brace in horizontal planes is not important to falsework stability.The length extruding from top horizontal bars should not exceeding 40 cm.
