Abstract: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.
Keywords:concrete braced frame; stock yard; horizontal load; earth pressure; soil arching effect
