超长混凝土框架结构温度应力实践

Practice of Temperature Stress in Ultra Long Concrete Frame Structure

某超长框架结构因功能需要,二层不设围护墙,季节温差大。用MIDASGen软件对板进行温度应力计算,用YJK软件对梁、柱进行温度应力计算,每种构件采用两种软件互相比对确保结果正确。根据荷载组合取包络值对结构配筋,并结合材料、施工工艺、构造措施等控制裂缝。

Due to the functional needs of an ultra long frame structure,there is no building exterior wall on the second floor,and the seasonal temperature difference is large.MIDAS Gen is used to calculate the temperature stress of the plate,and YJK is used to calculate the temperature internal force of the beam and column.Each component adopts two kinds of software to compare with each other to ensure the correct results.The structural reinforcement shall be taken according to the load combination envelope value,and the cracks shall be controlled in combination with materials,construction technology and structural measures.
