Abstract

A method for forming the complex composite cross-section by inserting the basic cross-sections includes such steps as defining various basic cross-sections and their reference points, dividing the composite cross-section into inclusion kind and spliced kind, defining the horizontal and vertical axises of the local coordinate system for composite cross-section, inserting the basic cross-sections according to determined parameters to form composite cross-section, and calculating the geometric and physical parameters of said composite cross-section.

Description

technical field [0001] The invention relates to a method for processing composite sections, in particular to a method for inserting basic sections to form complex composite sections, and belongs to the technical field of civil engineering. Background technique [0002] Steel concrete, steel pipe concrete, steel-concrete composite beams and other components are widely used in the project. These components contain more than two types of different materials and are composed of more than two basic sections. This type of member is different from a section composed of a single material, and needs special treatment in the structural finite element calculation. In other building structure finite element calculation software, the section type library is set for some commonly used composite sections. Each section parameter can be adjusted during use, but except for these parameters, the section type is determined and cannot be changed. [0003] Through literature retrieval of prior...
