Abstract:To investigate the mechanical behavior of castinsitu twoway concrete slabs reinforced by coldrolled deformed bars with doublewing，the test of two castinsitu twoway concrete slabs subjected to vertical uniform loads is carried out. The test results show that the castinsitu twoway concrete slabs reinforced by coldrolled deformed bars with doublewing have high loadbearing capacity and their loadbearing inspection coefficient can meet the requirement of the codes related，and that the mechanical behavior of the slabs is better at working loads when the design value of strength of bars is raised to 400N/mm2.
