Analysis and design of steel-concrete composite sandwich systems subjected to extreme loads

Kazi Md Abu SOHEL, Jat Yuen Richard LIEW, Min Hong ZHANG

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 3,   Pages 278-293 doi: 10.1007/s11709-011-0120-z

Abstract: This paper presents the design guide based on analytical, numerical and experimental investigation of Steel-concrete-steel (SCS) sandwich structural members comprising a lightweight concrete core with density ranged from 1300 to 1445 kg/m subjected to static, impact and blast loads. The performance of lightweight sandwich members is also compared with similar members with normal weight concrete core and ultra high strength concrete core ( = 180 MPa). Novel J-hook shear connectors were invented to prevent the separation of face plates from the concrete core under extreme loads and their uses are not restricted by the concrete core thickness. Flexural and punching are the primary modes of failure under static point load. Impact test results show that the SCS sandwich panels with the J-hook connectors are capable of resisting impact load with less damage in comparison than equivalent stiffened steel plate panels. Blast tests with 100 kg TNT were performed on SCS sandwich specimens to investigate the key parameters that affect the blast resistance of SCS sandwich structure. Plastic yield line method is proposed to predict the plastic capacity and post peak large deflection of the sandwich plates. Finally, an energy balanced model is developed to analyze the global behavior of SCS sandwich panels subjected to dynamic load.

Study on the interfacial shear behavior of steel reinforced concrete (SRC) members with stud connectors after fire

Zihua ZHANG,Junhua LI,Lei ZHANG,Kai YU

Frontiers of Structural and Civil Engineering 2014, Volume 8, Issue 2,   Pages 140-150 doi: 10.1007/s11709-014-0250-1

Abstract: Statically push-out tests of 20 steel reinforced concrete short columns (SRCSC) with stud connectors on the surface of shape steel after fire and two SRCSC under ambient temperature were carried out, in order to study the failure mode, load-slip relationship and the interfacial shear transfer of SRC members after fire. Experimental results show that the typical failure modes and load-slip curves of SRCSC after fire are almost the same as the case under ambient temperature. The interfacial shear transfer of SRCSC declines exponentially not only with the increase of the peak temperature the specimen experienced but also with the increase of the peak temperature duration. The interfacial shear transfer of the specimens with studs arranged at the steel web is much higher than those with studs arranged at the steel flange. Empirical formulas of SRCSC interfacial shear transfer after fire are proposed, and the calculated results generally agree well with the experimental results.
