In several seismic countries, residential buildings are constructed using both reinforced concrete (RC) and unreinforced masonry (URM) walls. Despite their popularity, there is a general lack of knowledge concerning the seismic behaviour of such mixed syst ...
Steel and steel-concrete composite bridges made of plate girders represent an economical structural form and are largely used for short and medium spans. Two parallel plate girders connected by cross-beams define a twin-girder bridge. This type of bridge t ...
In unreinforced masonry (URM) structures vertical walls are connected by horizontal spandrel elements. Spandrels have been subjected to extensive damage during earthquakes and are often the first elements within a URM building to crack or fail. If URM buil ...
Structural designers often face the challenge of developing forms optimal for a broad range of requirements, but inefficient in terms of structural behavior. In these cases, bending moments often occur under normal loading, resulting in oversized, inelegan ...
In codes the drift capacity of unreinforced masonry (URM) walls is often estimated as a function of the failure mode and the aspect ratio. The empirical relationships are based on results from quasi-static cyclic tests on single URM walls, which were teste ...
This paper discusses the findings of an experimental program that was conducted to investigate the behaviour of extended shear tab beam-to-column and beam-to-girder connections that are commonly used in North America. The laboratory results showed that ext ...
Arch-shaped members are used in many reinforced concrete structures such as tunnels, bridges, silos, or offshore constructions. They are generally designed to carry significant axial forces, and, in most cases, are not provided with transverse reinforcemen ...
In this paper an extensive research campaign aimed to define the mechanical performance of earth block masonry panels is presented. Uniaxial compression and diagonal compression tests were performed. The test results confirmed the brittle behaviour of eart ...
Arch-shaped members are widely used for construction of tunnels, bridges, silos and shells. These members are not typically provided with transverse reinforcement and may thus have a brittle behaviour at failure. When subjected to bending or shear, traditi ...
This study presents a dynamic-induced direct-shear model to investigate the dynamic triggering of frictional slip on simulated granular gouges. An incident P-wave is generated as a shear load and a normal stress is constantly applied on the gouge layer. Th ...
