Steel truss bridge rod piece check and calculation method and system

Abstract

The invention discloses a steel truss bridge rod piece check and calculation method and system and relates to the field of bridge design. The method comprises the steps of 1, on the basis of structure parameters and load of a steel truss bridge to be designed, calculating out a control inner force value of a rod piece to be checked and calculated in a main truss of the steel truss bridge; 2, on the basis of the control inner force value, utilizing a preset rod piece check and calculation model to obtain a check and calculation result of the rod piece to be checked and calculated. The control inner force value of the rod piece to be checked and calculated is calculated, control inner force is used as the preset rod piece check and calculation model to input, a check and calculation result of the rod piece to be checked and calculated is output, thus whether or not the design of the rod piece to be checked and calculated meets requirements is known, automatic check and calculation can be achieved, and the check and calculation result is precise and objective.

Description

technical field [0001] The embodiments of the present invention relate to the field of bridge design, and more specifically, to a method and system for checking and calculating members of steel truss bridges. Background technique [0002] Steel truss bridges combine the characteristics of steel and truss structures. Steel truss bridges have the advantages of strong spanning ability, suitable for industrial manufacturing, easy transportation and installation, and easy repair and replacement. Therefore, steel truss bridges have always played an important role in bridge construction. At the same time, the structure of the steel truss girder bridge is complex, and the internal force of the members in the main truss of the steel truss girder bridge may change due to changes in the load and foundation. In order to ensure the safety and reliability of the steel truss girder bridge after it is put into use, the At the beginning of the design, the members in the main truss must be st...

AI Technical Summary

Problems solved by technology

[0004] However, currently widely used bridge design software, such as Qiaotongtong, Bridge Master and Midas, etc., are not designed specifically for steel truss bridges.

Among them, Bridge Tong and Bridge Master are mainly used for the substructure design of bridges, and Midas is mainly used for the design of prestressed box bridges, suspension bridges, cable-stayed bridges and other special structural bridges, which cannot meet the requirements of the steel truss bridge main truss members. Checking requirements

In addition, manual checking is time-consuming and laborious, and the accuracy of the checking results depends on the experience and knowledge level of the checking personnel, which is not objective
