When testing multi-storey structures, most testing facilities require the testing of a reduced-scale model. A literature review on tests of scaled masonry structural components revealed that scaling of masonry was rather challenging and often significant differences in stiffness, strength and failure mechanisms between the different sized masonry were reported. This paper addresses the scaling ...

The seismic design of new retaining structures is usually performed following modern norms. Nonetheless, there are various monumental (e.g., fortifications) with high vulnerability, which must be protected against earthquakes, while exist several limitations on the type mitigation measures that can applied to such cultural heritage structures. present study investigates numerically response and...

A large part of the building stock in seismic-prone areas worldwide are masonry structures that have been designed without seismic design considerations. Proper seismic assessment of such structures is quite a challenge, particularly so if their response well into the inelastic range, up to local or global failure, has to be predicted, as typically required in fragility analysis. A critical iss...

This paper provides a comphrensive review of the critical aspects nonlinear modeling for evaluating seismic response masonry structures, emphasizing issues relevant to engineering practice. Currently, specialized technical community shares opinion that, performance-based approach, numerical models are only tools sufficiently effective support assessment existing buildings. However, their potent...

the objective of this paper is to present a new method for protecting the lives of residents in catastrophic earthquake failures of unreinforced masonry buildings by introducing some safe rooms within the buildings. the main idea is that occupants can seek refuge within the safe rooms as soon as the earthquake ground motions are felt. the information obtained from the historical ground motions ...

• Equivalent soil-structure interaction for modelling vibrations in masonry buildings. Preservation of the vibration properties leading to rocking and elongation. Non-linear model assess (light) damage. Decoupled soil structural models efficient, fast (probabilistic) analyses. Recent, light earthquakes induced by extraction gas north Netherlands have been linked light, mostly aesthetic damage t...

The seismic behavior of the infill masonry walls has a significant impact on global response reinforced concrete frame structures. One factor influencing its is existence openings in walls, such as doors and windows, which are crucial for performance. Although numerical simulation RC buildings with evolved significantly recent years terms micro- macro-modelling, most existing studies only relat...

Continuous rigid frame bridge is a common type of bridge in California, where is a seismically active areas. Main structural features of the bridge, including asymmetry, hinge structure, concretion of girder and piers affect the seismic response of the bridge significantly. In order to evaluate the safety of the bridge under earthquake, the nonlinear models of girder, limiting steels in hinge, ...

Progressive collapse is a kind of failure in which whole or large part of a structure collapse when a local damage occurs and distributes to other parts. Many researchers focus on the column removal analysis and study of the structure behavior under effect of gravity loads, so these investigations are mostly carried out on the tall building. Earthquake inspections indicate structural element ca...
