여러가지 形式의 格子桁橋에 對한 應力의 自動解析

Abstract

本論文의 目的은 格子桁橋의 設計에 있어서 Computer에 의한 새로운 방법이 紹介에 있다.

즉 지금까지도 格子桁橋에 쓰여지고 있는 Leonhardt, Homberg 方法은 適用 節次가 꽤 複雜하고 力學的으로 嚴密한 解를 産出시킬 수 도 있었다.

本論文의 結果로서는 任意의 格子桁橋에 對한 간단한 入力資料만으로 最大 Moment, Shear, Torsion, Deflection이 일어나는 格點들을 찾고 또 그 最大 Moment, Shear, Torsion, Deflection에 對한 影響線을 出力시키도록 하였고 또 각 部材에 對한 部材端力과 各 格點의 Deflection에 對한 影響線을 出力시키게 만들었다.

The purpose of this paper is to introduce a new method of designing the grid girdered bridge using computer program.

Leonhardt and Homberg's methods, which are presently used on designing of grid girdered bridge have various limitations in application. Futhermore these methods need complicated design procedures without giving exact solutions.

The results of the study eliminates all these inconveniences and enables us to obtain the nodal points and influence line data of maximum moment, torsion and deflection only by preparing simple program input data for design of grid girdered bridge.

The program also prints out the influence lines data for all member end forces and all nodal point deflections.
