Experimental characterisation of as-built and retrofitted timber-masonry connections under monotonic, cyclic and dynamic loading

In the province of Groningen (NL), where human-induced earthquakes take place due to gas extraction, a large part of the building stock is composed of brick masonry walls and timber diaphragms. In this framework, timber-masonry connections play a crucial role in the global seismic response of the buildings, but their properties and structural...

An analytical model describing the in-plane behaviour of timber diaphragms strengthened with plywood panels

Timber diaphragms in existing buildings are often too flexible in their plane, and can thus potentially cause out-of-plane collapses of walls during earthquakes. A very efficient retrofitting method to increase their in-plane stiffness and energy dissipation is the overlay of plywood panels. However, the usual characterization of the floors by...

Execution and reliability of slip resistant connections for steel structures using CS and SS (SIROCO)

SIROCO investigated the slip-resistant behaviour of carbon and stainless steel preloaded connections as well as the preloading behaviour of stainless steel bolting assemblies in principle. The slip factor test procedure according to Annex G of EN 1090-2 was investigated regarding the influence of the test speed, preload level, tightening method,...

Fatigue behaviour of a welded I-section under a concentrated compression (wheel) load

This paper deals with the evaluation of fatigue cracks under a concentrated compression (wheel) load in an I-section with full penetration welds between the web and flange. The objective is to investigate whether cracks stop or nearly stop when they have grown through the residual tensile stress field. These experimental investigations are...

Mechanical behaviour of Transparent Structural Silicone Adhesive (TSSA) steel-to-glass laminated connections under monotonic and cyclic loading

Steel-to-glass laminated connections, which have recently been developed, limit stress intensifications on the glass and combine strength and transparency. Transparent Structural Silicone Adhesive (TSSA) connections have been used in several projects worldwide; however, the hyperelastic and viscoelastic nature of the material has to date not...

Fatigue behaviour of a welded I-section under a line load in compression

This paper is part of an evaluation of fatigue cracks in a crane runway girder with full penetration welds between the web and flange. The fatigue analysis of this actual crane runway girder is described in [1]. The investigation described in this paper deals with additional experimental tests on equivalent welded I sections on scale of...

Determination of the shear strength of tropical hardwood timber

The current shear strength values for high density tropical hardwoods are very low compared to the values for softwoods, according to European strength class tables. The reason for this is that standardized tests according to European standard EN 408 have not been performed yet for tropical hardwoods. In this...

Tensile tests on 2-pin connection aluminium profiles

Verbindingssysteem voor rondhout

The connecting system for rod-shaped construction components (1) comprises connecting (3) and coupling devices for the rods and a separate coupling block (4) to which coupling devices (7) are fixed for coupling of connecting devices. The coupling devices are located on two opposite sides of the coupling block. Coupling blocks in the system are...
