桥梁工程概论之桥梁设计计算（一）
摘要： 简支梁计算>计算内容简支梁计算内容1、需要计算的部位：主梁、横梁、桥面板；2、主要荷载：结构重力、预应力、活载、日照温差；3、计算项目：主梁强度365JT设计、验算；横梁强度设计、验算；桥面板强度设计、验算；主梁变形计算、预拱度计算；计算方法简支梁计算方法主梁恒载内力：按实际结构尺寸计算恒载集度，计算应力时将荷载作用在结构上直接计算，但应注意要根据按365JT施工方法确定何种荷载作用在何种截面上。主梁预应力内力：简支梁属于静定结构，预应力只产生出内力，不产生二次力效应。主梁......

Introduction of bridge engineering bridge design calculations (1)
Abstract: Simple Beam Calculation> Calculation of the contents of the contents of a simple beam calculations, need to calculate the area: the main beams and cross beams, deck plate; 2, the main load: Structural gravity, prestress, live load, temperature sunshine; 3, computing : main beam intensity 365JT design, checking; beam intensity of design, checking; bridge panel strength design, checking; main beams calculated camber calculation; calculated beams calculated main beam dead load internal forces: the actual structure size calculation of dead load sets and calculating the stress will load directly in the structure calculation, it should be noted to be under construction by 365JT which loads determined what the cross section. Internal force of prestressed girder: beams are statically determinate structure, prestressed produce only internal forces, and no secondary force effect. Girder ......
