摘要
为掌握拉结钢筋在多孔砖砌体水平灰缝中的粘结锚固性能,确定拉结钢筋的最小埋置(锚固)长度,进行了27组试件的静力拉拔试验研究,得到了砂浆强度、竖向压应力以及钢筋锚固长度对拉结钢筋粘结锚固性能的影响规律,并验证了现行规范所规定的拉结钢筋埋置长度对多孔砖砌体的安全可靠性。
Through test analysis on the anchoring behavior of 27 groups of binding steel bar embedded in the horizontal mortar seams of perforated brick masonry, a law was obtained for the impact of mortar strength, vertical compressive stress and the steel bar length on the anchoring behavior of the steel bar, meanwhile relia- bility of the bar embedment length specified in the code to the safety of the perforated brick masonry was demonstrated.
