要旨 | INTRODUCTION A steel-concrete sandwich structure is a composite structure in which double steel skins and concrete core behave monolithically. The steel plates have two roles of per-manent formwork and reinforcement. This system has been applied to port and harbor facilities since the early 1980s,and has potential applications in submerged tunnel con-struction and also in nuclear containment and blast resistance structures. To study further the basic structural behavior of steel-concrete sandwich structures,a series of tests has been undertaken. Parts of the tests have been already reported. Here, two specimens are added and an attempt to describe the beam behavior is presented. This study shows also some analytical results concerning essentially the specimens without shear reinforcement and the influence of shear connectors. CONCLUSION Some experimental and analytical results of steel-concrete sandwich beams have been described. Beams without shear reinforcement had a shear failure in a tied-arch mode when shear span to depth ratio a/d was 2 and in a diagonal tension failure mode when a/d=3 to 4.Concrete may have some defects and cause a small shear rigidity of connectors in tension zone at the beginning of loading. Further work on linkage element model is currently under way. |
