composite steel concrete composite floor used mainly in the commercial and office building has lighter weight and is considered very economical. the light weight natures of this type of floor causes some vibration problems when it is subjected to loadings such as human footstep loading. the dynamic characteristics of these floors are dependent on several parameters such as joist span, girder sp...
This paper presents an ant colony system model for cost optimization of a composite floor system based on the load and resistance factor design (LRFD) specification of the AISC. The model formulation includes the cost of concrete, steel beam, and shear studs. The objective function is considered as the cost of the structure, which is minimized subjected to serviceability and strength requiremen...
Concrete-timber composite floor is a construction technique combining two materials, concrete and timber, connected together using some form of interlayer shear connectors either positioned discretely or continuously along the span of the floor. The interlayer connections provide the desired composite action, where the degree of this composite action is governed by the types of connection syste...
In the last few decades, application of lightweight cold-formed composite steel–concrete structural systems has constantly been increasing within field engineering. This can be explained by efficient material usage, particularly noticeable when using built-up sections and innovative types shear connections. paper summarises an overview development floor systems. Additionally, it provides backgr...
Abstract To provide the foundations for economic and social prosperity, countries worldwide need to be making a term investment in their building assets. However, there is lack of systematic approach, such as manufacturing innovations, maximize values components materials its entire lifecycle. Steel-concrete composite floor systems are one most cost-effective construction multi-storey steel bui...
Experimental tests of a composite concrete-cross-laminated timber (CLT) floor system were conducted. The floor system was constructed with 5-ply CLT panels (6.75 in. thick) made composite with a 2.25 in. thick reinforced concrete topping slab. Four series of tests were performed using different specimen configurations and laboratory testing methods. Tests included: (1) Comparative one-way bendi...
Creep response of a full-scale floor system fabricated with composite wood I-joists and oriented strand board (OSB sheathing) was measured for 280 days at sustained uniform loads of 20 psf (0.96 kPa). Creep responses of bare I-joists and 3-joist T-beams with OSB sheathing (glued and unglued tongue and groove sheathing joints) were measured under similar load levels and duration. The creep defle...
