Optimization of multi-directional fiber architecture for resistance and ductility of bolted FRP profile joints

In view of the low structural efficiency of bolted joints in pultruded fiber-reinforced polymer (FRP) profiles with mainly unidirectional (UD) fiber architecture, off-axis plies were considered as an effective way to improve bolted joint performance. An ex ...

Modelling Workflow for Segmented Timber Shells using Wood-wood Connections

Yves Weinand, Julien Gamerro, Nicolas Henry Pierre Louis Rogeau, Petras Vestartas

This paper presents a modelling method based on planarization for double-curved segmented timber shell made from quad polygons and assembled by wood-wood connections. The inspiration is taken from timber dome structures, where solid timber walls were built ...

Enhancing Punching Strength and Deformation Capacity of Flat Slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Raffaele Cantone

Punching reinforcement systems have significantly developed in recent years as they allow enhancing the punching resistance of slab-column connections as well as their deformation capacity. These systems, with varying geometry and layout, normally consist ...

Experimental testing and simulation of bolted beam-column connections having thick extended endplates and multiple bolts per row

Alain Nussbaumer, Gary Scott Prinz, Luís Costa Borges, Shyam Khadka

Retrofit of existing steel buildings often requires strengthening of the connection regions. One common connection, the bolted beam-column connection, is often strengthened in design using stiffened extended endplates, or with continuity plates welded betw ...

Influence of Residual Stresses on Fatigue Response of Welded Tubular K-Joints

Claire Acevedo

Seeking light and transparent bridge designs, engineers and architects have found an efficient and artistic way to fulfill their requirements: steel tubular bridges. In these modern tubular truss bridges, welded K-joints have been shown to be critically su ...

A critical examination of the size effect correction for welded steel tubular joints

Alain Nussbaumer, Luís Costa Borges, Ann Schumacher

Welded circular hollow section (CHS) joints typical to bridge construction have been examined in an experimental, numerical, and analytical study with respect to their fatigue strength. Evidence from this study has indicated lower fatigue strength for join ...
