On the role of equivalent strut models in the seismic assessment of infilled RC buildings

Further Developments of a Simplified Modelling of Infilled Frames for Reinforced Concrete Buildings

“…In the field of the approaches of macro modelling, the Equivalent Strut is widely used to simulate the effects of infill panels on the global response of individual frames and / or buildings [2,4,11,15,19,27]. These studies are important in order to establish the retrofit interventions needed to ensure the seismic safety to the deficient buildings [9,10].…”

“…The above parameters depend by models and experimental tests reported in the literature, which especially in the case of existing structures, cannot be generalized to all the possible cases, but are reliable only in few cases that are similar to those on which they were defined [4]. The laboratory tests cannot be generalized because are expensive.…”

A Parametrical Analysis for the Rotational Ductility of Reinforced Concrete Beams

“…The code, consistently with the methodologies developed in literature, proposes two main approaches: a mechanical-empirical approach, based on plastic hinge length concept, and a purely empirical approach [4][5][6][7][8][9][10]. In addition, it should be noted that precisely defining the plastic rotation in the non-linear field is a crucial step in the seismic assessment of buildings and infrastructure [11][12][13][14].…”

Seismic Modelling and Analysis of Masonry Building in Aggregate: A Case Study

“…The application of the mentioned RBSM model is particularly effective since it allows to considerably reduce the computational burden while keeping, at the same time, the information about the meso-scale effects of the masonry behavior. It has been, in fact, fruitfully employed both for the analyses of complex, real buildings [19][20][21][22] and when it is used to perform a large number of analyses for calibrating simplified macro-models of masonry panels [28,29].…”
