Cantilever slabs are among the most vulnerable structural elements at blast loading. As they are indispensable to most structures, it is important to investigate the behaviour of cantilever slabs in a blast environment ...

Evaluation of existing steel bridges becomes vital due to natural aging, increasing load spectra, deterioration caused by corrosion, increasing seismic demand, and other problems. In the result, bridge structures exposed ...

Over the past decades there have been many damage examples of older steel bridge structures due to corrosion around the world. Even though there are some published methods to assess the strength reduction due to corrosion ...

Abstract: This paper presents a new fatigue model to predict life of steel bridges considering the effect of high amplitude loading. It consists of a modified strain-life curve and a new strain based damage index. Modified ...

High performance concrete (HPC) exceeds the properties and constructability of normal concrete. Normal and special materials such as fly ash, micro silica and nano silica are used to make these specially designed concretes ...

Railway lines consist of steel truss bridges which are very old and have many problems due to inadequate maintenance system or need to increase its capacity to carry higher loads. To undertake above challenges there should ...

Since 1990s various methods have been proposed by researchers to estimate the fatigue strengths of metals at gigacycle fatigue regime (number of cycles > 108). As testing of metals in the gigacycle regime requires much ...

The mega event of Indian Ocean Tsunami 26th December 2004, stressed the need for assessing tsunami hazards in vulnerable coastal areas in Sri Lanka. Two major areas of the management of disaster prevention are to evacuate ...

Bridges face the risk of being damaged by natural and manmade disasters. Old bridges are more vulnerable in such situations. The common practice is removing these damaged bridges and constructing new ones. However, ...

This paper presents a methodology and results of evaluating damaged building extraction using an object recognition task based on Differential Morphological Profile (DMP) for Very High Resolution (VHR) remotely sensed ...
