[摘要]  由于建筑層高的限制,傳統(tǒng)的抗剪連接件所需的混凝土樓板厚度將受到影響。針對(duì)該問(wèn)題設(shè)計(jì)了一種新型不連續(xù)鋼板抗剪連接件,解決了界面抗剪和鋼梁與混凝土掀起脫落的問(wèn)題。在此基礎(chǔ)上,采用有限元軟件ABAQUS,對(duì)不同形式的抗剪連接件進(jìn)行彈塑性分析。研究表明,本文提出的新型連接件原理簡(jiǎn)單、安全可靠,具有較大的工程應(yīng)用價(jià)值。

Abstract: Due to limitations the thickness of the concrete slab on building storey height were required, traditional shear connectors were difficult to meet regulatory requirements. The new shear connectors composed with rebar and discontinuous steel plate were designed to solve the problem of interfacial shear and lift off the steel and concrete problems. On this basis, using the finite element software ABAQUS, with the stud shear connectors contrast, the shear performance of the new shear connector was analyzed, and the feasibility of the new shear connector is proven.

Keywords: shear connector;discontinuous flange plate steel;push-out test;numerical simulation
