摘要:
为研究冷弯薄壁型钢组合楼盖中螺钉连接的受力性能和破坏模式,对4个冷弯薄壁构件与组合板采用自攻螺钉连接的推出试件进行了单调静载试验。通过推出试验研究了不同抗剪构造措施和不同楼板面材料对推出试件抗剪刚度、抗剪承载力及粘结性能的影响。试验结果表明:石膏基自流平砂浆推出试件在发生局部粘结破坏后,砂浆面板逐步退出工作,试件因压型钢板屈曲和螺钉倾斜而破坏;混凝土推出试件在发生局部粘结破坏后,螺钉连接未发生破坏,试件因混凝土面板脱落而破坏;在组合板中加入抗剪构造可提高试件的粘结性能和抗剪刚度,但会降低抗剪承载力。采用《冷弯薄壁型钢结构设计规范》(GB 50018-2002)计算推出试件中单颗螺钉的抗剪承载力较为合理。
