STRESS-STRAIN BEHAVIOR OF CONNECTIONS FOR PARTIALLY COMPOSITE WOOD-CONCRETE FLOORS AND DECK SYSTEMS

摘要

A composite layered system made of wood and concrete is an effective means forrncombining the structural and non-structural benefits and eliminating some disadvantages of each material.rnThis paper address the mechanics of an innovative interlayer-connection detail for transmitting interlayerrnforce and creating composite action. Prior laboratory work and analytical beam and plate modelingrnconfirmed the effectiveness for overall composite action. Initial work to examine the mechanics of therninterlayer force transfer, surface to surface contact stresses at the notched-anchor connection and nearbyrncontinuum behavior is described. A finite-element formulation that includes contact elements and otherrnfeatures is being utilized. To date the model is successful within the early limitations enacted for initiallyrnsimplifying the simulation.
