预压装配式预应力混凝土框架拟动力试验及分析
|
摘要
预压装配式预应力混凝土框架采用工厂化生产的预制柱和预制预应力梁,运至现场直接吊装,梁柱就位后,将后张预应力筋穿过梁柱预留孔道,对节点实施预应力张拉预压。后张预应力筋在施工阶段作为拼装手段,在实用阶段参与承受梁端弯矩,构成整体受力节点和连续受力框架,既克服了装配式节点受力可靠性差的缺陷,又解决了预应力混凝土框架难以装配的问题,形成了预制预应力混凝土装配式整体框架,为预应力结构的工业化生产开辟了新的途径。
本文通过一榀两层双跨预压装配式预应力混凝土框架的拟动力试验,研究和分析了在竖向荷载和水平地震荷载作用下预压装配式预应力混凝土框架的受力性能和变形能力。并使用平面弹塑性动力分析程序DRAIN-2DX(1993)对试验框架进行弹塑性静力和动力时程计算机模拟,把动力时程分析部分的分析结果与拟动力试验结果相比较,可以较好的吻合。
本文的研究表明,预压装配式预应力混凝土框架具有良好的抗震性能。
Prestressed Subassemblage concrete frame is assembled by precast presstressed beams and columns with tendons in the joints of the frames. These beams and columns are hoisted in sit and the tendons are passed through the moire pips. So prestressing force is brought to the joints of the frame. These tendons also can assume the moments at the end of the beams in ordinary condition. By way of these tendons, precast beams and columns can be assembled conveniently, and the joints and frames are monolithic and continuous. Consequently, compared with common reinforced concrete frames, this kind of frame systems possess higher reliability and sloved the problems in the process of assembling Prestressed Concrete frames. Prestressed Subassemblage concrete frame explores a new way for industrial production of prestressed structures.
This paper based on the pseudo-dynamic test of one Prestressed Subassemblage concrete frame. We Studied and analysed the stress performance and deformability of Prestressed Subassemblage concrete frame under vertical load and horizontal seismicload, and used the plane elastoplasticity dynamical analysis program Drain - 2dx (1993)which can be used to proceed elastoplasticity statical and dynamics time-history computer modeling for the test frame. Compared the results of dynamics time-history analysis with the outcome of quasi-dynamic test, we found it dovetailed very well.
All the studies show that the Prestressed Subassemblage concrete frame has better seismic performance.
