| 摘 要： | 本文介绍了在顺德电厂实测获得的各种动力参数,通过分析,找出了副厂房主、次梁产生裂缝的原因。进行了动力拟合计算,得出了垂直和水平的激振力以及相应的动位移、动内力。提出了主、次梁粘钢加固设计方案,进行了实际工程加固、动力模型试验及有限元计算。判明了加固后粘钢在振动情况下钢板是否剥落以及由于刚度改变,是否会发生“共振”现象。

| Abstract: | In this paper, the kinetic parameters obtained form the Shunde Electric Power Plant are introduced and the cracking reasons for the beams of lts auxiliary workphop are fornd. The vertical and level exciting forces, the Corresponding dynamic deflections and the dynamic internal forces are obtained by using the kinetic calculation. The design scheme of steel-bonded reinforcement for the beams is propsed. The re-inforcement of realistic construction, the dynamic model test and the dynamic finite element calculation are conducted. Under the vibratory circumstances after steel-bonded reinforcement, it can be iudged that whethher the steel plates peeled off and whether the resonance of the auxiliary workshop occurred ouing to the change of the structural stiffness. |
