开洞梁力学性能求解与影响参数分析

Solution of Mechanical Properties of Hole-web Beams and Influencing Parameters

以开洞梁内力和抗剪承载力计算为出发点,研究两种不同抗剪承载力计算方法,分析其合理性,并应用在具体计算实例中,计算不同开洞尺寸和位置的抗剪承载力变化规律。结果表明,开洞尺寸越大,梁抗剪承载力越小;开洞离梁边缘越近,梁抗剪承载力越差。

The hole-web beam internal force and shear strength calculation is thought of as the starting point, the calculation methods of two different shear capacity are studied, and they are applied to calculation of concrete because feasibility of the calculation methods , and applied it in the concrete calculation. The variation of shear bearing capacity with different hole size and position is studied. Re- sults show that the larger the size of openings, the smaller the shear bearing capacity; the more close to beam edge, the worse shear bearing capacity.
