【摘要】 考虑连续组合梁由于负弯矩区混凝土翼板开裂而造成梁刚度的改变,及混凝土应力、应变非线性关系而对其弹性模量进行修正以及型钢与混凝土翼板之间相对滑移而造成的附加挠度等因素的影响,导出了连续组合梁挠度的计算公式.经验证,计算值与实测值吻合良好.更多还原

【Abstract】 Based on discussions on following factors:(1)the alteration of stiffness of beam caused by crack and failure of concrete on the negative moment region;(2)the concrete modulus of elasticity rerised by considering the non-liner relationship of concrete;(3)the additional deflection caused by slipage between still beam snd concrete slab,the calculation formula of deflection of the continuous composite beam was put forward.It was proved to be right.更多还原
