Description

含有CFRP-PCPs复合筋的试件
技术领域
本发明属于建筑技术领域，尤其涉及到CFRP-PCPs复合筋试件。
背景技术
混凝土是现代建筑工程中常用的建筑材料之一，目前对混凝土材料耐久性的理论和试验时土木工程研究的热点。在使用阶段，由于荷载作用等原因，会出现受力隙缝，所以，大多数的混凝土结构实际上都是带裂缝工作的。因此，在含有CFRP-PCPs复合筋的混凝土材料试验研究中，通过预设裂缝的混凝土试件研究开裂状态下混凝土材料的力学性能和耐久性对预测混凝土结构的服役寿命具有重要的意义。CFRP-PCPs(Carbon Fiber Reinforced Polymer-Prestressed Concrete Prisms)复合筋是指CFRP筋与高性能活性粉末混凝土组合在一起的筋材。
发明内容
本发明旨在克服现有技术的缺陷，提供含有CFRP-PCPs复合筋的试件，具有制作简单、试验结构准确的特点。
为了解决上述技术问题，本发明提供了如下的技术方案：
含有CFRP-PCPs复合筋的试件，包括截面为矩形试件，试件两端设置有端支座，试件由混凝土、钢筋笼、CFRP-PCPs复合筋、波纹管构成，钢筋笼为两根CFRP-PCPs复合筋、四根纵筋和若干箍筋绑扎而成，四根纵筋分布于箍筋顶点内侧，箍筋底部均匀分布有两根CFRP-PCPs复合筋。
纵筋为螺纹钢筋。
CFRP-PCPs复合筋表面粘贴有包裹纱布的应变片。
与现有技术相比较，本发明具有如下的有益效果：
本试件制作简单、试验结果准确，价格低廉，可以为研究开裂混凝土的耐久性与服役性能提供试验基础。根据试验需求放置不同根数复合筋以及对于复合筋中不同张拉控制预应力CFRP筋的基础上，对构件的受力过程、破坏过程、极限承载力、裂缝和变形特点进行试验研究。
