摘要
首先将混凝土中的栓钉类比为土体中的桩基;然后根据m法建立了混凝土中栓钉变形的平衡微分方程;再采用幂级数法对该平衡微分方程进行求解,得到了栓钉剪切刚度计算的通用公式及荷载-滑移本构关系曲线。将本文推导的理论结果与国内外文献的结果进行对比分析,验证了本文结果的正确性。
Firstly,the shear connectors buried in concrete are regarded as the piles buried in the solid.Then,an equilibrium differential equations of shear connector is conducted based on the m method assumption for pile.After that,an analytic method for calculating the slip stiffness of shear connector has been proposed by solving the differential equations using the power series expansion,and a constitutive relation between load and slip is established.The accuracy of the proposed method is verified by comparing with the theoretical results and experimental results proposed by literatures.
