Abstract

Abstract

Based on the analysis of the basic characteristics of the buckled metal roof panel, the weak points of its wind-uplift resistance were theoretically analyzed. It was pointed out that the weak link was that the stiffness of metal plate was insufficient and the redundancy of fastening method was insufficient. Wind-uplift test on its prototype plate system showed that mid-span deformations of the plate were too large when the system was damaged and the initial damage occured at the fastening position. According to the analysis of the weak points of wind-uplift resistance and the failure characteristics of the prototype plate system, the wind-uplift resistance of the strengthened plate system was tested. Comparing with the wind-uplift resistance capacity of the prototype system before reinforcement, the results of series tests showed that the static wind-uplift resistance capacity could be increased by 139% and 121% by using the long and short trough-pass beads respectively. Based on the theoretical analysis and test results, suggestions on application scope and reinforcement optimization measures of this type of plate were put forward.
