摘要
在车间增设光伏设备,既能满足车间用电需求,又能降低能耗和碳排放,为保证厂房结构安全,需对厂房进行承载力检测与安全性评估。针对门式刚架厂房增设光伏设备可能引发的结构安全问题,从构件截面尺寸、钢材强度、钢柱垂直度等方面进行检测,并使用PKPM软件进行增设光伏荷载承载力验算。结果表明,钢梁抗弯强度应力比达1.37,钢柱抗弯强度应力比达1.23。采用间接加固技术,通过钢梁增设隔撑、柱间增设系杆、梁柱增设斜撑加固方式,使钢梁应力比降低至0.77(降幅43.8%),钢柱应力比降低至0.76(降幅38.2%)。研究成果可为类似建筑物检测提供借鉴。
Installing photovoltaic equipment in the workshop can not only meet the electricity demand of the workshop,but also reduce energy consumption and carbon emissions.To ensure the structural safety of the factory building,it is necessary to conduct load-bearing capacity testing and safety assessment.In response to the structural safety issues that may arise from the addition of photovoltaic equipment to portal frame factory buildings,inspections were conducted from the aspects of component cross-sectional dimensions,steel strength,and steel column verticality,and PKPM software was used to verify the load-bearing capacity of the added photovoltaic load.The results show that the stress ratio of the bending strength of steel beams is 1.37,and the stress ratio of the bending strength of steel columns is 1.23.The indirect reinforcement technology is adopted to reduce the stress ratio of steel beam to 0.77(a decrease of 43.8%)and the stress ratio of steel column to 0.76(a decrease of 38.2%)by adding spacer braces to steel beams,tie bars between columns,and slant support to beams and columns.The research results can provide reference for similar building inspections.
