随着我国高层钢结构建筑增多,对于粘弹性阻尼钢结构建筑的非线性静力分析十分必要。本文基于有限元理论对粘弹性阻尼钢结构高层建筑进行非线性静力分析,研究结果表明:在恒轴力荷载作用下,钢结构框架的应力、应变最大位置在柱脚和梁端,框架的荷载位移滞回曲线是比较饱满的梭形;粘弹性阻尼器布置在底部位置的减震效果优于没有布置粘弹性阻尼器的建筑,且位移和变形较小;粘弹性阻尼器对高层钢结构的最大剪力和最大位移有明显的抑制作用。
With the increase of high-rise steel structures in our country, nonlinear static analysis of viscoelastic damped steel structures is very necessary. In this paper, based on the finite element theory, the nonlinear static analysis of viscoelastic high-rise building with damping steel structure is carried out. The results show that under the constant axial load, the maximum stress and strain of the steel frame are between the column foot and the beam end, The displacement hysteresis curve is full fusiform; the viscoelastic damper is better than the one without the viscoelastic damper in the bottom position, and the displacement and deformation are less; the viscoelastic damper has a better damping effect on the high-rise steel structure The maximum shear and maximum displacement have obvious inhibitory effect.
