Experimental and theoretical analysis on wind-uplift resistance of standing seam color steel roof system with curved stainless steel plate support
摘要
Abstract
In recent years,the wind-induced damage to standing seam metal roofs because of insufficient bearing capacity of T-code support to resist wind uplift often occurs.To effectively improve the wind-uplift resistance of standing seam color steel roofing system,a curved stainless steel plate support was designed.In order to obtain the damage mode,force mechanism and wind-uplift resistance of the standing seam color steel roof system with curved stainless steel plate support,and to verify the reliability and effectiveness of the support,wind uncovering tests on four roof specimens were carried out.At the same time,a finite element analysis model was established,and the accuracy of the analytical model was verified by the experimental data.The influence of parameters such as roof panel thickness,roof panel width and longitudinal spacing of the support on the wind-uplift resistance of the roof system was studied.The results show that there are two damage modes of the standing seam color steel roof system with curved stainless steel plate support the upper curved arc section of the support is straightened and unbuckled,and the lower curved hook of the vertical component is straightened and unbuckled at the vertical section of the base where the curved hooks are buckled.In addition,the wind-uplift resistance of the roofing system can be increased by reducing the width of the roof panel and the longitudinal spacing of the support,increasing the thickness of the roof panel,and installing additional wind-resistant clips.Based on the test and finite element simulation,the correlation between various factors was obtained by correlation analysis,and formula for calculating the wind-uplift resistance of this roof system was proposed.The results obtained from the proposed formula are in good agreement with both the experimental and simulated results.关键词
