Carrying Capacity of Semi-Rigid Joint of Timber-Concrete Beams

Abstract

The aim of this article is a presentation of the results of laboratory tests and numerical and analytical modeling of timber-concrete composite beams with semi-rigid joints made of steel plates and convex nails. Due to good quality of used materials, composite timber-concrete constructions are considered a suitable solution for new buildings and reconstructions of ceiling constructions of residential and civil buildings. There are numerous ways to create a connection (joint) between timber beam and concrete slab. The methods of coupling are more and more sophisticated which carries considerable demands on control of implementation and technological practice.

Improvement of Two-by-Four Timber System Stiffness by Using Polyurethane Foam as a Cladding Insulation

“…According to present standards racking strength and rigidity depend mostly on cladding joint strength [1][2][3]. Main goal of this article is to prove mechanical properties (racking strength, rigidity) of common used two-by-four wall panel with polyurethane foam insulation and wall panel without insulation.…”
