【摘要】 本文用数值迭代法对钢——砼组合梁截面的弯矩—曲率关系和权限弯矩进行了计算分析。从理论上校核了用来确定组合梁极限抗弯强度的简化塑性理论。计算结果和分析表明,数值迭代法是计算组合梁截面曲率的有效方法。在已知滑移应变的情况下,数值迭代和数值积分计算可以较精确地估算不完全剪力连接钢—砼组合梁的挠度。更多还原

【Abstract】 An approach of trial and error to calculate the resistant moment and curvature of cross Sec- tion in composite steel—concrete beams is proposed.The suggested method verfies the simple plastic theory used in determining the ultimate flexrual strength of composite steel—concrete beams theoretically.It is believed that,the approach of trial and error is a useful means in predicting the curvature,and numerical integration can be rcasonably used in estimating the deflection in composite beams with incomplete shear connection,provided the slip strain is known.更多还原
