摘要:
针对以钢骨混凝土桁架为主框架梁的角筒式巨型框架结构的具体特点,通过静力弹塑性分析及与振动台试验结果的对比,主要对巨型框架结构的静力弹塑性分析中模型的建立、不同水平加载方式的影响、巨型框架结构的出铰次序和位置、结构侧移、主要杆件内力及谱分析进行了探讨和研究.结论表明,巨型框架结构的整体抗震性能较普通框剪结构有较大提高; 杆系模型静力弹塑性分析可较好地模拟出巨型框架结构中塑性铰出现的次序和位置、结构主要杆件内力以及基底剪力与控制点位移的相互关系; 应注意加强桁架层上下层的抗剪延性措施.
Abstract:
The essay discusses in detail about the characteristics of the angle-canister pattern mega-frame with steel reinforced concrete truss as the major frame beam. A discussion and research for the model establishment in the static pull-over analysis of the mega-frame, the effects of different leveled load methods, the ream output sequence and position of the mega-frame, side-move of the construction, the internal force of the main staff element and spectrum analysis were carried out based on a comparison between the results of static push-over analysis and shaking table experiment. It is concluded that the integral seism-resistance performance of the mega-frame structure increases greatly comparing with that of the common frame shear structure. And also the static push-over analysis of the bar model can imitate well the output sequence and position of the plastic ream and the relationship between the force of the main component together with the shear in the foundation of the structure and the displacement of the controlling point. Attention should be paied to strengthen the measures of shear resistance ductility between the stories up and down the braced truss.
