| 摘 要： | 提出了上部框架结构和地基基础共同作用的一种简化计算方法，采用变弹模轴压杆模拟地基作用，上部结构引入等效斜压杆来考虑砖填充墙和框架的共同作用。工程算例计算结果表明，相对不均匀沉降计算结果与实测结果接近，内力计算结果与结构实际损伤规律相符。

Calculation of additional internal forces of RC frame filled with brick wall due to uneven ground settlements |
| |
| Abstract: | A simplified model to calculate uneven settlements and internal forces in RC frame filled with brick wall is proposed in this paper,considering superstructure-foundation-soil interaction.The interaction between columns and filled masonry is taken into account by simplifying the brick wall as compression diagonals,and the interaction between foundation and soil is taken into account by simplifying the soil below foundation as elastic-modulus-varied axial compression bars.The calculation results for a mill building located in Shanghai have good match with that observed in the site. |
