海港工程结构构件几何尺寸不定性分析

Indeterminate Analysis of Geometrical Dimensions of Structural Members for Harbour Engineering

本文介绍以可靠性理论为基础的概率极限状态设计法中影响抗力的因素之一——结构构件几何尺寸的不定性分析,经对我国华南、华东沿海港口及预制厂的主要构件,如梁、板、桩、码头跨度等的调查和测量,在取得60批共3400多个数据的基础上进行数理统计来确定构件几何尺寸的统计参数和概率分布类型。

On the basis of reliability theory and by using probability limit state design, this paper gives description on the method of indeterminate analysis of structural members, in wbich their resistance forces are greatly in fluen-ced.According to the ivestigation and measurement of great numbers of structural members, such as beams, slabs, piles aud wharf panels, from the coastal harbours in South and East China and relevant fabrication shops, the authors collect altogether more than 3400 data, with 50 groups, and then carry out mathematical statistics in order to secure the statistical parameters and probability distribution in determining the geometrical dimemsions of structural members.
