Bayon temple, Angkor, built in the late 12th century to the early 13th century, is a masonry temple made of sandstone which has deteriorated possibly due to rain, plants, settlements, and so on. Strong winds blowing more than 20m/sec were observed in the rainy season, which may cause vibration of the structure either directly or via ground motion, we may add wind induced vibration to the list o...

This paper describes an experimental program that deals with retrofitting of infill un-reinforced masonry walls (URM) with Fiber Reinforced Polymer (FRP). The primary objective of this research is to develop a retrofit strategy that while economical will minimize the influence of the retrofit on the overall performance of structural frames in predominant seismic regions. Allowing some damage to...

This paper focuses on producing a natural hydraulic lime (NHL) mortar with metakaolin, expanded perlite and tuff additives for the purpose of repairing historic masonry. The experimental study was based laboratory tests determining mechanical physical properties NHL mortars mineral additives, under standard water curing conditions at 7, 28 90-day testing periods. Following preliminary selecting...

In the last decade, displacement-based seismic design procedures have been recognised to be effective alternatives to force-based design (FBD) methods. Indeed, displacement based design (DBD) may allow the structural engineer to get more realistic predictions of local and global deformations of the structure, and hence damage, under design earthquakes. This facilitates the achievement of perfor...

Three-dimensional computer models used in the classroom may help increase student understanding of new and complex course material, and provide an opportunity to enhance visuospatial skills. Students lacking these abilities may have difficulty visualizing construction systems and components. This study explores the results of a survey conducted in the Fall of 2009 as part of a curriculum develo...

Non-linear dynamic time history analysis is considered as the most advanced and comprehensive analytical method for evaluating the seismic response and performance of multi-degree-of-freedom building structures under the influence of earthquake ground motions. However, effective and accurate application of the method requires the implementation of advanced hysteretic constitutive models of the ...

An effective approach for strengthening masonry buildings is to apply shotcrete reinforced with mesh on the surface of the wall. It is not possible to assess the behaviour of coated walls solely using analytical approaches based on simple equations of theory of elasticity without the use of numerical methods. Unreinforcced masonry wall is modelled in this study using the finite element softwar...
