ABSTRACT Composite steel and concrete floors are often susceptible to excessive vibrations caused by human activities because of their slender structural elements. To achieve a precise evaluation, it is necessary to incorporate the effects of dynamic

Abstract Global second order effects in reinforced concrete buildings can be estimated using numerical or simplified methods, such as the γz coefficient, presented in the Brazilian standard. This paper proposes a new simplified parameter, which is d

Reinforced concrete structures may need repair in order to ensure the designed durability. The assessment of the structural condition usually is made in loco, but sometimes numerical analyses are required as a low cost and effective preliminary diagn

The use of fibre reinforced polymers (FRP) for increasing the strength of reinforced concrete (RC) structures became a usual method. FRP presents easy application and demands low space and provide significant strength increase. Usually, the decision

The analysis of reinforced concrete structures can be performed by means of experiments or numerical studies. The first way is usually quite expensive, so the second one sometimes is a good option to understand the physical behaviour of actual struct

Sismos são eventos naturais, causados principalmente devido ao movimento relativo entre placas tectônicas (sismos interplacas) e em falhas entre blocos rochosos (sismos intraplacas), ou induzidos pela atividade humana. Pode-se observar uma relaçã

Analysis of RC structures subjected to seismic loads vary greatly around the world, from simplified static models to more advanced methods, which take account of real dynamic loads and the nonlinear response of structures. As a recent theory, lumped
