Seismic Behaviour of Square CFT Beam-Columns Under Biaxial Bending Moment 双向弯矩作用下方钢管混凝土梁柱的抗震性能
Research on Bearing Capacity Calculation of Concrete-Fille Rectangular Tube; Seismic Behaviour of Square CFT Beam-Columns Under Biaxial Bending Moment 方矩型钢管混凝土柱承载力计算的理论研究双向弯矩作用下方钢管混凝土梁柱的抗震性能
By changing the angle of seismic waves in the single-dimensional Time-History analysis, the most disadvantaged angle and the most negative value of bending moment, shear are founded in the analysis. The single dimensional Time-History analysis results are compared with the single dimensional response spectrum results. 通过改变地震输入角度对结构进行单维时程分析,找出了各墩底单维地震输入下弯矩、剪力最不利输入角度和最不利值,对比了单向反应谱与单维地震输入结果。
Top in the main tower will withstand seismic loading have a greater bending moment, tensile stress will appear, seismic design should take note. 主塔塔顶在承受地震荷载时会产生较大的弯矩,还会出现拉应力,抗震设计时应该注意到这一点。
