in this paper, an approximate method is proposed for determining sway of multistory rc buildings subjected to various types of lateral loads. the calculation of both fundamental period and stability index in rc building requires the sway term at each story level. using approximate method design engineers can estimate sway terms at each story level. the developed analytical expressions are inser...

Unreinforced Masonry infill walls (URM) are commonly used in the Reinforced Concrete (RC) framed structures as interiors and exteriors partition walls. Although they usually are not considered in the structural analysis and design, their influence on the seismic performance of the framed structures is significant. A common practice in the modern and old RC buildings is to remove the URM walls i...

Over one-quarter of steel produced annually is used in the construction of buildings. Making this steel causes carbon dioxide emissions, which climate change experts recommend be reduced by half in the next 37 years. One option to achieve this is to design and build more efficiently, still delivering the same service from buildings but using less steel to do so. To estimate how much steel could...

The main purpose of this work is to compare different criteria for the seismic strengthening of r.c. framed buildings in order to find the optimal combinations of these retrofitting techniques. To this end, a numerical investigation is carried out with reference to the town hall of Spilinga (Italy), a r.c. framed structure with an L-shaped plan built at the beginning of the 1960s. Five structur...

This paper describes the development of a numerical finite element algorithm used for the analysis of reinforced concrete structure equipped with shakes energy absorbing device subjected to earthquake excitation. For this purpose a finite element program code for analysis of reinforced concrete frame buildings is developed. The performance of developed program code is evaluated by analyzing of ...
