摘要
以黄石市华新骨料场中的混凝土支撑框架为例进行受力分析试验,采用静止土压力理论、库伦土压力理论分析了支撑框架受到骨料的水平荷载。结合试验和理论结果,进一步讨论了土拱效应对框架受力的影响,分析了骨料场中框架破坏的原因。基于研究成果,建议了堆料场中框架所受水平荷载的计算方法,并给出相应支撑框架的设计建议。
Mechanics experiment was conducted towards the concrete braced frame of Huaxin stock yard in Huangshi city.Static earth pressure theory and Coulomb’ s earth pressure theory were applied to analyze horizontal loading on the braced frame.Based on the test and theory results,the influence of the soil arching effect on mechanics of frame was discussed,and the causes of frame failure in stock yard were analyzed.Based on the analysis results,the calculation method of the horizontal load on the frame in the stock yard was proposed,and the design suggestions of the corresponding braced frame were given.
