6、BSTRACT American Society of Civil Engineers Standard for the Structural Design of Composite Slabs, ASCE Standard Practice for Construction and Inspection of Composite Slabs (ASCE 3-91 and ASCE 9-91 respectively) presents standards for the structural design and testing of composite slabs and for good

7、 construction dards are included. The “Standard for the Structural Design of Composite practice and inspection procedures. In addition, commentaries on both stan- Slabs” (ASCE 3-91) and its “Commentary” cover such topics as loads, construc- tion stage, strength design, service load design, test proc

8、edures, and test results evaluation. The “Standard Practice for the Construction and Inspection of Composite Slabs” (ASCE 9-91) and its “Commentary” discuss such topics as damage control, connections, concrete placement, shore removal, holes and hole reinforcement. These standards are written in suc

9、h a form that they may be adopted by reference in a general building code.
