组合结构读入元在桥梁上的应用

The Application of Composite Structure Reading Blements to Bridge Engineering

本文针对箱梁与实体墩，承台与桩基等不同类型单元之间如何建立读入元作了研究，同时采用ＳＡＰ—５程序和读入元在ＩＢＭ４３３１机上作了变截面箱梁与实体墩组合结构空间分析．通过实例探讨了读入单刚前后结构位移和内力的变化及其变化范围．

This paper studies how to set up the reading Clemens between box girder and solid pier or between bent caps and piles, etc., namely between the clements which differ types. Three dimensional analysis of the composite struc- ture, with varied section box girder and solid pier, is completed by use of the SAP-- 5 program and the reading clements on IBM-4331 Computer. The illust- rative example shows not only the variations of the structural displacements and internal forces with the introduction of reading elements and in to siructural analysis but their varying ranges as well.
