1、单轨吊车梁选用表（检索号： ）国 家 电 力 公 司 西 南 电 力 设 计 院二00二年十二月 成都单轨吊车梁选用表（检索号： ）总工程师：设计总工程师：主任工程师：科长：主要设计人：前 言以极限状态设计方法编制的钢结构设计规范（GBJ1788）已经颁布，我们根据火力发电厂工程中结构设计的需要，按新的钢结构设计规范编制出此院控标准设计单轨吊车梁选用表,以供我院土建结构专业人员在火力发电厂工程设计中使用。由于现行规范对单轨吊车梁的设计未作详细规定，编制过程中有关计算公式是按照钢结构设计手册（GBJ1788版，中国建筑工业出版社）进行的，其中，许多地方采用了近似方法。目前，有关单轨吊车梁设计方面

2、的参考资料不多，再加上编者的水平有限，此选用表中的缺点和不妥之处在所难免，希望使用者批评指正。设 计 说 明一 适用范围：1 本设计是西南电力设计院院控标准设计，仅供本院土建结构专业人员使用。2 电动单轨吊车起重量和梁的跨度范围起重量：2.5kN100kN直线梁跨度：3m10m圆弧梁半径：1.0m10m3 单轨吊车分手动和电动两种，本设计仅按电动单轨吊车设计。在设计手动单轨吊车梁时，使用者可酌情参考。二 设计依据1 规范建筑结构荷载规范（GB500092001）钢结构设计规范（GBJ1788）2 参考资料钢结构设计手册（GBJ1788版，中国建筑工业出版社）建筑钢结构设计手册（冶金工业出版社）

3、三 计算方法1 一般假定起重量和单轨吊车自重量均按活荷载考虑，分项系数1.4单轨吊车梁自重按永久荷载考虑，分项系数1.2；动力系数1.05，计算挠度时不考虑分项系数和动力系数；计算强度、稳定性和挠度时，钢材的强度设计值和截面惯性矩分别乘以磨损折减系数0.9；梁的挠度控制值1/400；多于三个支点的弧线梁假定按三个支点考虑，并在计算时将自重的均布荷载先略去不计，待弧线梁内力求得后在乘以自重系数1.05；弧线梁的最大弯矩和双力矩均产生于跨中集中荷载作用处，故只按该点内力作为控制条件计算承载力。2 符号约定单轨吊车额定起重量和自重单轨吊车梁自重、分别为梁截面绕主轴的惯性矩、抵抗矩和半截面面积矩、工字
