Abstract

Abstract

Generally,a coupler steel tube falsework just bears the vertical loads,however,in some structure construction,the falsework should carry a horizontal load from lateral concrete pouring.Taking a subway project for example,the stability bearing capacity of the falsework when it bears a double-direction load is calculated,whose result is compare with that of its carrying both two-way load and a horizontal load,so that a parameter from building of falsework is got.The result of a numerical analysis shows that stable bearing capacity of the falsework under double-direction load is lower than its carrying a vertical load only.So,a series of reliable measures are needed to maintain the stability of the whole structure.
