Several concrete structures in tectonically active regions of the world are exposed to chloride ingress from seawater, saltwater, and other sources, making them vulnerable corrosion-induced deterioration. Although it is well-known that deterioration influences force-displacement behaviour corroded components under cyclic loading, no adequate provisions have been incorporated into state-of-pract...

The concept of controlling seismic waves is in progress and first full-scale experiments had confirmed the interest which we can have for this new axis of research. The possibility of imagining a seismic 2D or 3D metamaterial made of a grid of inclusions or empty boreholes in the soil, interacting with a part of the earthquake signal is becoming realistic. Here we show the dynamic response of a...

The bearing capacity factors for a rough strip footing placed on rock media, which is subjected to pseudo-static horizontal earthquake body forces, have been determined using the lower bound finite element limit analysis in conjunction with power cone programming (PCP). mass assumed follow generalized Hoek-Brown (GHB) yield criterion. No assumption needs be made smoothen GHB criterion and conve...

By Timothy Phillips Vaughan, MS. Washington State University May 2010 Chair: David I. McLean This research evaluated the structural performance of reinforced masonry shear walls conforming to requirements given in the 2008 MSJC Building Code Requirements for Masonry Structures under cyclic lateral loading. Seismic design provisions in the 2008 MSJC provide prescriptive requirements for three di...

One of the serious damages of tremendous earthquakes is the damage to bridges as the major components in an    arterial road network, as relief operation is interrupted following cutting roads. Regardless of the magnitude and severity of an earthquake, other factors are also important in the strength and seismic performance of concrete bridges. Freezing-thawing cycles are among the factors, whi...

This paper provides an experimental analysis of timber-framed walls, coated with carbon fibre-reinforced polymers (CFRP) strengthened fibre-plaster boards. The presented wall elements are usually used as main bearing capacity elements in the construction of prefabricated multi-level timber residential buildings. Since the tensile strength of fibre-plaster sheathing boards (FPB) is approximately...
