| 摘 要： | 对4片1/2模型节能砌块隐形密框墙板进行偏心受压试验,分析各试件的破坏过程、协同工作性能、破坏形态及承载力,得出承载力计算公式.研究结果表明,计算结果与试验结果吻合较好,且偏于安全,该公式可用于节能砌块隐形密框墙板的偏心受压承载力计算.随着偏心距的加大,试件由小偏心受压逐渐变为大偏心受压,其破坏荷载逐渐减小,而延性逐渐加大,符合钢筋混凝土构件的破坏规律.密框和砌块间可以很好地协同工作;试件的偏心受压破坏属于材料破坏范畴,不会发生试件平面外纵向弯曲破坏.

| Abstract: | Four pieces of 1/2 scale energy-saving block and hidden multi-ribbed frame wall models are studied experimentally under the eccentric compression.Failure processes,cooperative working action,failure modes and bearing capability are analyzed to obtain the bearing capability calculation formula.Research indicates that the result of the calculation formula agrees conservatively with the test results.And the formula may be used to calculate the bearing capability of this type of wall.With increasing the eccentr... |
