The punching shear capacity of concrete slabs reinforced with 3CR12 corrosion resistant stainless steel and carbon steelFourie, Johan Becker 06 December 2011 (has links)
M.Ing. / In this study a comparison is made between the punching shear capacities of square slabs reinforced with 3CR 12 corrosion resisting stainless steel and high tensile strength carbon steel. A square column 11 0 mm x 11 0 mm is used to simulate the point load on the slab. Three different slab depths were chosen for the experimental procedure. The South African concrete design specification SABS 0 I 00, the Eurocode concrete design specification and Menetrey's design model are used to determine the theoretical punching shear capacities of the slabs. It is concluded in this study that the procedures described in the concrete design codes and by Menetrey to determine the punching shear stress of concrete slabs reinforced with high strength carbon steel reinforcing bar compare well with the experimental results when 3CR I 2 corrosion resisting steel is used as reinforcing bar in concrete. The experimental results do not compare well with the theoretical results when the new Eurocode is used.

Preslab - micro-computer analysis and design of prestressed concrete slabsDu Toit, André Johan January 1988 (has links)
Bibliography: pages 128-132. / A micro-computer based package for the analysis and design of prestressed flat slabs is presented. The constant strain triangle and the discreet Kirchhoff plate bending triangle are combined to provide an efficient "shell" element. These triangles are used for the finite element analysis of prestressed flat slabs. An efficient out-of-core solver for sets of linear simultaneous equations is presented. This solver was developed especially for micro-computers. Subroutines for the design of prestressed flat slabs include the principal stresses in the top and bottom fibres of the plate, Wood/Armer moments and untensioned steel areas calculated according to Clark's recommendations. Extensive pre- and post-processing facilities are presented. Several plotting routines were developed to aid the user in his understanding of the behaviour of the structure under load and prestressing.

New Test for Shear Connectors in Composite Construction.Lam, Dennis January 2000 (has links)
no / Composite beams formed by connecting the concrete slabs to the supporting steel beams have been in use for many years. Much of the research into this form of construction has concentrated on the more traditional reinforced concrete and metal deck construction. In composite beam design, the strength of the shear connector is of great importance since longitudinal shear forces must be transferred across the steel-concrete interface by the mechanical action of shear connectors. The shear strength and stiffness of the connection is not only dependent on the strength of the connector itself, but also on the resistance of the concrete slab to longitudinal cracking caused by the high concentration of shear force at each connector. Present knowledge of this behaviour is limited to shear connectors in solid reinforced concrete slabs and concrete slabs with profiled sheeting, little information is given for the shear connector capacity on composite steel beam with precast hollow core slabs. A new horizontal push off test is proposed to determine the shear capacity of the connector on the composite beams with precast concrete hollow cored floor slabs. The results showed the new test is compatible with all type of floor and shear connectors, and can replace the existing vertical push off tests.

Demountable reinforced concrete slabs using dry connectionAlmahmood, Hanady A.A., Ashour, Ashraf, Figueira, Diogo, Yildirim, Gurkan, Aldemir, A., Sahmaran, M. 06 May 2023 (has links)
Yes / This paper presents an experimental investigation of a new dry connection for reinforced concrete slab elements. Seven full-scale slabs were tested; one slab was monolithic as control specimens, while the other six were assembled using top and bottom steel plates joined by high tensile steel bolts. Two scenarios were proposed for the connection, a simple bolted connection, and a connection with a shear key. The parameters studied were the use of stirrups at the connection section, the step size of the shear key as well as the bolt diameter and number. The test results showed that using a shear key at the assembled section in demountable slabs is more efficient than the simple bolted connection, providing higher flexural stiffness, load capacity, and less deflection. However, increasing the shear key step size improved the flexural performance of the demountable slabs. In addition, adding stirrups to the assembled section enhanced the flexural stiffness and the total load capacity of the demountable slabs. Furthermore, the predictions for the moment capacity and deflection demountable slabs have reasonably good agreement with the experimental results but require additional calibrated data from experiments to be generalized. / Department for Business, Energy and Industrial Strategy (BEIS)
