- Using the ansys finite element analysis software , this paper analyzes reinforcement plate of different length welded to crane girder crack and find out the girder ' s stress and deformation
摘要采用ansys有限元分析软件，对因出现裂纹的起重机主梁而添加的补强板进行系列计算，得出修补后主梁裂纹的应力及应力强度因子的变化规律。 - This product is mainly used for reinforcing various pre - stressed concrete structures such as large bridges , crane girders , cement power poles , pre - stressed concrete pipes , frames of multi - story factory buildings , etc
本品主要用于各种预应力混凝土结构的配筋。如大型桥梁、吊车梁、水泥电杆、预应力混凝土水泥管、多层厂房框架等。 - Dynamic test has been performed on three strengthened girders after they were being put into service . according to the measured data from the dynamic test and the calculated results of the proportion of the load distribution on steel diagonal braces and steel crane girders as well as the increased carrying capacity after strengthening in consideration of the principle of cooperative work between braces and crane girders , the feasibility , rationality , and economy of this strengthening scheme have been verified . this scheme can be applied extensively to strengthen crane girders system including concrete crane girders system hereafter
最后结合对已经加固施工并投产使用的3榀钢吊车梁的现场实际动测结果，按考虑下部钢斜撑与钢吊车梁二者协同工作的原理对钢吊车梁与下部斜撑之间的荷载分配比例以及加固后钢吊车梁的承载能力进行了进一步的计算验证和对比分析，论证了采用钢斜撑方案加固已有钢吊车梁的合理与有效性。 - The strategy on repair and reinforcement on steel crane girder structures in service based on fatigue dynamic reliability is analyzed in the paper . considering the benefits of repair and the long - term economic affection after repair and reinforcement , using the fatigue dynamic reliability as constraint condition , thinking of that the sum of benefits of repair and reinforcement as object function , the optimization model is put forward . then it is used to an certain crane arc ends repair an reinforcement
5 、基于疲劳动态可靠性，对在役钢结构吊车梁的维修加固策略进行了探讨，考虑维修加固效益和维修加固后的经济影响，提出了以疲劳动态可靠性为约束，以维修加固总效益为目标函数的优化决策模式，并通过某钢厂圆弧端吊车梁的维修加固实例验证，可为工业建筑吊车梁的设计，管理和维护提供依据。 - Based on practical project of inspecting , appraising and reinforcing a main heavy factory building , especially its steel crane girder system , of the second steel mill belonging to taiyuan steel & iron corporation , whose technology renovation leads to increase tonnage of many heavy cranes and vertical load of frame - bent structure , first the structure and its members were investigated , inspected , calculated and analyzed , and their reliability was appraised respectively and the strengthening projects or the measures to remedy were given . then , in accordance with the requirement to strengthen the girders under non - stop production , the feasibility of strengthening the crane girders by adding steel diagonal braces underneath the existing girders has been studied by inspecting and evaluating the strengthening effect of the crane girders and comparing with other reinforcing scheme
本文结合太钢(集团)有限公司第二炼钢厂主厂房由于生产工艺改造要求，加大多台重型吊车吨位及bc跨( 1 ) ( 8 )轴线框排架各层竖向(设备)荷载后，对厂房结构，尤其钢吊车梁系统进行检测鉴定与加固设计的实际工程，首先对厂房结构进行了现场调研、技术检查、测试以及内力和承载能力的计算与分析(考虑抗震) ，并根据检测、计算与分析结果，对厂房结构、构件的可靠性进行了评定，并综合提出鉴定结论和加固处理建议。
