Serviceability Performance of Timber Concrete Composite Floors

Structural Tests of Concrete Composite - Cross - Laminated Timber Floors Final Report

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...

FEM models of composite timber-lightweight concrete floor systems

Paper presents the main principals in designing wood-lightweight concrete composite floor structures using FEM models. All design-related analyses are performed by means of the FEA COSMOS/M program. Paper emphasises some important details in FEM model design (how to choose appropriate finite elements for different types of materials, how to connect concrete slab and timber beams to work togethe...

Behavior of Composite Timber-Concrete Beam with CFRP Reinforcement

Serviceability design of residential wood framed floors in Canada

The serviceability design of wood-framed residential floors in Canada has taken a departure from use of the traditional deflection criterion based on maximum deflection under uniform loading. This departure is based on laboratory and field research in the 1970's and 1980's which, in 1990, led to adoption of a new criterion in the National Building Code of Canada. In part, this criterion is base...

Prediction of Acoustic Performance of Composite Steel Floors

One method of constructing lightweight concrete floors in residential dwellings is to use a trapezoidal profile steel pan as a permanent form for a relatively thin pour of concrete. The resulting structure has enhanced stiffness to weight ratio due to the composite action between the steel and concrete, and the inherent improved stiffness of the profiled cross section. However the floor is stro...
