摘　　要：为了解决钢结构工业厂房屋面加装光伏板后檩条承载能力不足的问题,提出3种檩条加固方式。通过ABAQUS有限元分析,对比分析3种加固方式的加固效果和加固机理。进一步开展参数分析,探究关键参数对加固檩条受弯性能的影响规律,最终基于数值仿真结果对加固檩条有效长度系数进行数据拟合。研究结果表明,3种加固方式均满足屋面安装光伏板的承载能力要求,其中隅撑加固优化了屋面檩条传力路径,加固方式最为合理和经济。参数分析表明,檩条端部至支撑点长度和隅撑规格对檩条的承载能力影响显著。基于参数分析结果,拟合隅撑加固檩条有效受力长度系数的数学公式,从而为钢结构光伏屋面檩条加固提供设计参考。In order to address the issue of insufficient load-bearing capacity of purlins in steel industrial buildings after the installation of photovoltaic panels on the roof,three purlin reinforcement methods were proposed.The effectiveness and reinforcement mechanisms of the three methods were compared and analyzed through finite element analysis using ABAQUS.Further parameter analysis was conducted to explore the impact of the parameters on the bending performance of the reinforced purlins.Finally,based on the numerical simulation results,a fitting model was established for the effective length factor of the reinforced purlins.The research results showed that all three reinforcement methods met the load-bearing requirements for installing photovoltaic panels on the roof.The corner brace reinforcement optimized the load transmission path of the roof purlins and was found to be the most reasonable and economical reinforcement method among them.Parameter analysis revealed that the length from the end of the purlin to the support point and the angle steel specifications had a significant impact on the load-bearing capacity of the purlins.Based on the parameter analysis results,a mathematical formula was fitted for the effective length factor of the corner brace reinforced purlins,providing design references for the reinforcement of steel structure photovoltaic roofs.
