冷轧带肋钢筋混凝土受弯构件的试验研究

AN EXPERDIMENTAL STUDY OF COLD ROLLED WITH RIBS REINFORCED CONCRETE MEMBERS SUBJECTED TO BEND

用冷拔钢丝制成的双钢筋混凝土构件和用冷轧带肋钢筋制成的混凝土构件，均能节约钢材，降低造价；这两种结构已有研究￣［１］。用冷轧带肋钢筋制成的双钢筋，更能节约钢衬，可制成更加节约钢材的结构，但日前尚未有研究报导。本文试验研究了冷轧带肋双钢筋混凝土的受弯构件，结果表明这种构件在承载力和裂缝宽度方面，均具有更好的性能。图５，表２，参２。

Bisteel reinforced concrete members made of cold drawed steel wireand steel reinforcement with ribs were studied in referenee one, the result showedthat the steels was saved and the cost was lowed.However, Bisteel reinforeementrnembers made of cold rolled steel reinforeement with ribs with the save of moresteels were rep orted.Bisteel with reinforced concrete members subjected to bend arestudied on the bss is of experiment in this pap er,the results show that the type ofmember has excellent properties in the bearing capacity and the crack width.5figs.,2tabs,,2refs.
