Abstract: This study contributes to the improvement of capacity models for older-type RC members to be used in the seismic assessment of existing RC structures. A database of experimental tests on RC columns with plain bars is ...

Abstract: Unreinforced masonry (URM) structures have shown their vulnerability to major events like as earthquakes, severe wind, blast, and impact. The present work started from experimental programs available in scientific literature ...

Abstract: Masonry structures have demonstrated their seismic vulnerability during recent world seismic events. This paper investigates in-plane seismic performance of unreinforced masonry (URM) walls before and after they are retrofit ...

Abstract: Previous experimental studies, conducted by some of the authors, on in-plane response of tuff masonry walls strengthened with an innovative cementitious matrix composite grid (CMG) system confirmed that the CMG system could ...

Abstract: This paper aims to appraise the opportunities provided by a new class of composites based on using basalt fibers bonded with a cement-based matrix as an innovative strengthening material for confinement of reinforced ...

Abstract: Negative bending moments acting in the support regions of continuous composite beams generate tensile stresses in the concrete slab and compressive stresses in the lower steel profile. As a result the mechanical behavior ...

Abstract: In this paper a consistent method including damage criteria in the seismic response of single-degree-of-freedom systems is proposed. The method allows the determination of suitably modified strength or displacement inelastic ...

Abstract: Internal transverse steel reinforcements (e.g., stirrups) are the main internal devices that prevent the longitudinal steel bar buckling, but in many existing reinforced concrete (RC) structures the amount and the spacing ...

Abstract: This paper deals with an innovative technique for strengthening reinforced concrete (RC) structures using steel-reinforced polymer (SRP) materials. The results of an experimental campaign using RC beams strengthened in ...
