文档介绍：摘要
本毕业设计承担水利水电枢纽工程中水电站厂房结构设计工作。
本设计水电站厂房总厂66m,跨度18m,设计柱距6m,屋架采用平坡梯形钢屋架,吊车梁和排架结构均为钢筋混凝土结构。结构设计是保证安全的重中之重,其原则是确保厂房的安全、适用、耐久,同时使设计经济合理。根据已知其他资料进行结构设计,主要内容有:确定水电厂房典型横剖面图,进行厂房结构平面布置,吊车梁设计与配筋,平坡梯形钢屋架设计,排架结构设计与柱子配筋,并绘制相应施工图。
吊车梁系直接承受吊车荷载的承重结构,是厂房上部的重要结构之一,本设计吊车梁为简支结构,截面采用T型。钢屋架设计中,假定所有杆件位于同一平面内,杆件重心线汇交于节点中心,且各节点均为理想铰,不考虑次应力的影响,应用内力系数法计算屋架杆件的轴心力。排架结构简化为平面结构进行计算,即假定排架柱上端与屋架铰接,下端与基础顶面固结,屋架两端处柱的水平位移相等,不考虑排架的空间作用。
关键词:厂房结构平面布置、梯形钢屋架、吊车梁设计、排架柱结构设计
Abstract
This graduation design for building structure design of water conservancy and Hydropower Engineering in hydropower station.
The design of hydropower station plant 66m, span 18m, the design of space 6m, the slope of trapezoid steel roof truss, crane beam and frame structure for the reinforced concrete structure. Structural design is the priority among priorities to ensure the safety, the principle is to guarantee the safety, applicability, durability, and make the design reasonable economy. The structure design according to the known data, the main contents are: the typical cross section of hydropower plant, layout of workshop structure, crane beam design and reinforcement, slope of trapezoid steel roof design, layout design and structural frame pillar reinforcement, and the corresponding construction drawing.
Bearing structure of crane beam is directly under the crane load, is an important structure of the workshop, the design of crane beam is simply supported structure, cross section by T. Steel truss design, assuming that all the members in the same plane, member center lines converge on the centre of the node, and each node is the ideal hinge, without considering the effects of secondary stress calculation of axial force, the application frame internal force coefficient method. Bent frame structure is simplified as a plane structure is calculated, which assumes that the bent frame column is hinged at the lower end and roof, and the top surface of the horizontal displacement of foundation consolidation, equal
