装配式钢结构系统选型及节点连接技术分析

装配式钢结构模块化施工技术作为一种先进的施工方法,与传统现场施工技术相比,它提供更快的施工、更安全的制造、更好的质量控制和更低的环境影响。随着结构系统形式和材料的不断发展,装配式模块化施工方法在高层钢建筑中的实际应用潜力巨大。本文介绍了钢建筑装配模块化施工技术的最新进展,重点介绍装配式钢结构系统和节点连接技术的比较与分析,对高层装配式钢结构建筑的施工具有一定的参考价值。

EXPERT SYSTEM AND ITS APPLICATION IN THE SELECTION OF PIT RETAINING STRUCTURES

This paper describes the development of an expert system(ES) on earth retaining structures for the selection and design.The ES retaining is an interactive menudriven system and consists of two main parts—the selection part,selectwall and the design part.Selectwall is developed using the knowledge base and it makes a choice of the most appropriate retaining structure.The design part is developed by three independent subprograms which perform detailed design including strength,deformation,stability of the retaining structure.The calculation results are illustrated by plotting the diagram.Using this program,the design procedure of the retaining structure can be performed automatically.
