摘要
研究不同梯格尺寸双钢筋试验梁的工作特性,确定用冷拉螺纹钢筋制作双钢筋的合理梯格及加工工艺参数,分析用Φ12双钢筋配筋的双钢筋砼受弯构件的刚度,提出大直径双钢筋砼受弯构件的刚度计算公式,并分析其裂缝发展特征.
in this paper, based on the experimental research on the structural behavior oftested beams reinforced by bi-steel with different sizes of ladder- frame. the reasonable size of lad der-frame and welding parameters are determined. Next. the rigidity of fiexural members reinforced by big-diameter bi-steel (Φ12) under service loading is investigared. and the formulas forcalculating the rigidity of such members are presented. In addition, the cracking characteristics ofthe fiexural member with bi-steel are analysed.
