【摘要】:采用非線性有限元方法,對提出的一種新型鋼梁-型鋼混凝土剪力墻組合節(jié)點(diǎn)進(jìn)行低周循環(huán)加載非線性研究,并通過參數(shù)化分析,探討混凝土強(qiáng)度等級、混凝土保護(hù)層厚度、鋼材強(qiáng)度等級、端板厚度和摩擦因數(shù)等因素對該類節(jié)點(diǎn)抗震性能的影響。結(jié)果表明:提出的這種新型蓋板犬骨式鋼梁-型鋼混凝土剪力墻組合節(jié)點(diǎn)滯回曲線飽滿,抗震性能優(yōu)越;混凝土保護(hù)層厚度、鋼材強(qiáng)度等級和端板厚度等因素對節(jié)點(diǎn)的抗震性能影響較大。
[Abstract]:Nonlinear finite element method is used to study the nonlinear loading of a new type of steel beam-steel concrete shear wall composite joint under low cycle cyclic loading. Through parametric analysis, the effects of concrete strength grade, concrete protective layer thickness, steel strength grade, end plate thickness and friction coefficient on the seismic performance of this kind of joint are discussed. The results show that the hysteretic curve of the new composite joint of canine steel beam and steel concrete shear wall is full and the seismic performance is superior, and the thickness of concrete protective layer, steel strength grade and end plate thickness have great influence on the seismic performance of the joint.
