摘要:
运用ANSYS软件计算分析了双撑杆横张智能预应力简支梁中智能伸缩杆的布置方式、预应力索的截面面积以及智能伸缩杆的顶升方式这3个因素对系统消耗的能量、智能伸缩杆的杆力和智能伸缩杆的伸长量这3个性能评价指标的影响.分析结果表明:智能伸缩杆的初始杆长越长,性能指标越好; 智能伸缩杆应对称布置在梁跨度的1/4和3/4附近; 预应力筋的截面抗拉刚度越大,性能指标越好; 不同顶升方式之间,智能伸缩杆耗能的差别很小,可采用同步顶升.
Abstract:
Based on the design parameters of smart prestressed beam with two struts, the impacts of strut’s collocation and tendon’s area and jack-up’s mode on the system energy dissipation and the strut force and the strut extension are analyzed by using ANSYS software. The results show that the longer the initial length of struts, the better the performance index of smart prestressed beam, and the struts should be symmetrically disposed in the 1/4 and 3/4 of the beam span.In addition,the higher the tensile stiffness of prestressing tendon, the better the performance index of smart prestressed beam, and the difference of system energy dissipation is little between the different jack-up modes.
