| 摘 要： | 密肋复合墙体是密肋壁板结构体系的主要受力构件之一,其受力特点与抗震性能是密肋壁板结构体系计算理论与设计方法研究的基础核心.通过对密肋复合墙体在水平低周反复荷载作用下的试验研究,分析墙体的水平承载能力及侧向变形性能.应用人工神经网络对密肋复合墙体的水平承载力及顶点侧移进行预测,平均相对误差为5.4%.提出了密肋复合墙体的抗侧刚度退化曲线和骨架曲线模型,并给出统一的表达式,为进一步的研究提供了基础.

| Abstract: | Multi-ribbed composite slab(MCS) is one of main bearing member in multi-ribbed composite slab structure(MCSS).The force transferring characteristics and seismic properties of the slab are key points of computational theory and design method of MCSS.Based on the tests of MCS under low-cycle lateral loading,lateral resistance and deformation performance of the slab are analyzed in this paper.Using the neural networks,lateral resistance and drift of the slab are evaluated,and the results indicate that the average error is 5.4%.The model of skeleton curve and the curve of stiffness degradation of the slab are presented,and the uniform expressions are given,which provides the foundation for successive study. |
