Abstract: Monotonic static loading tests of four 1∶ 0. 55 scale model of SRC beam-slab members under eccentric tension were conducted． Experimental research mainly focused on the failure modes，crack distribution and width of cracks， bearing capacity，etc． The experimental results indicated that the crack widths under load cases of practical engineering were smaller than the limit value of Code for Design of Concrete Structures ( GB 500102012) ． Referring to the formula for crack width of SRC flexural members in technical specification for steel reinforced concrete composite structures ( JGJ 1382001) and combining with the formula for crack width of reinforced concrete members under eccentric tension in Code for Design of Concrete Structures，the formula for maximum crack width of eccentric tension SRC members under short-term loads was proposed，whose calculated results were compared with the test ones．
