组合结构中两类新型剪力连接件的研究分析

Analysis of Two Types of New Shear Connector in Composite Structure

钢—混凝土组合结构是在集合钢结构与钢筋混凝土结构优点的基础上发展起来的一种结构,该类结构中不同材料力学性能组合利用的好坏主要取决于材料交界面处剪力连接件的选用。本文基于组合空腹板架结构及组合梁结构,对两类新型剪力连接件进行理论分析与试验研究,分析两类新型剪力连接件的力学性能及破坏形态。

Steel-concrete composite structure is a new type of structure that in collection of the advantages of steel structures and reinforced concrete structures.The use of mechanical properties of different materials is based on the choice of shear connectors near the material interface.This paper is based on composite open-web plate frame and composite beam.We do the theoretical analysis and experimental study of two types of shear connectors and research their mechanical properties and failure modes.
