【摘要】 以徐州某公寓楼为例,建立结构框架力学模型,并利用ANSYS有限元软件分别计算了加固前和采用静压桩支托纠偏加固方案后的结构应力和振型等。加固前后的结果比较说明:加固后结构最大应力减小,强度、刚度和稳定性都有提高,加固措施是有效的。更多还原

【Abstract】 Taking the apartments in Xuzhou as an example,this paper builds up a series of mechanical models of frame structure.Based on these models,structure stresses and mode shapes,respectively before and after static pile pressing under pinning reinforcement,can be calculated by use of the software ANSYS.The compared results show that,the maximum stress reduces after the structure is reinforced,and meanwhile the intensity,stiffness and stability are all improved to a certain extent.In a word,such a reinforcing measure is effective.更多还原
