The majority of the building-stock from before 1900 has been erected with natural hydraulic lime-based mortars in massive masonry. Due to the low modulus of elasticity of lime-based mortars there has never been a need for dilation joints in old masonry structures. Changes in shape as a result of expansion and contraction, due to hot/cold cycles, could be “followed” by these masonry structures w...
ABSTRACT: This paper explores the behavior of infill masonry structures strengthened with a new type of Fiber Reinforced Polymer (FRP) strengthening system with high fracture strain know as PET (Polyethylene Teraphthalate) and a new near-surface mounted (NSM) Carbon fiber strengthening system using a cementitious material as the adhesive as compared to a Glass Fiber (GFRP) strengthening system ...
Silos are structures that are used for storing different types of granular material. Dynamic behavior of silos under seismic loads is very complex. In this paper seismic behavior of steel silos with different height to diameter ratios is investigated by considering granular material-structure interaction using ABAQUS finite element package. Silo wall is modeled by shell elements and its behavio...
The Azores archipelago is a small and remote region with low population levels where the issues of sustainability and autonomy have a lways been important and present s ignif icant economic consequences. Currently, the construction industry uses many imported products; however, masonry products are almost exclusively provided by local industries. For its production, masonry uses a natural volca...
Post-installed elevator projects have grown significantly in recent years response to the problem of insufficient vertical traffic capacity existing buildings, but research on seismic performance post-installed structures has been relatively limited. This study takes a 26-story-frame shear wall structure as an example. The characteristics this before and after installation elevators were analyz...
Performance-based seismic design (PBSD) method has been widely recognized in recent years, it can be used for the future structural design. And the direct displacement-based design method (DDBD) is one of the most effective ways to implement the performance-based seismic design (PBSD) theory in current. In this paper, aiming to the composite frame consisting of composite beams and continuous co...
Masonry buildings constitute a significant portion of the architectural heritage all over world, also in regions affected by high seismic hazard. Since this constructional material is characterized lack tensile strength, as well small deformation capacity, masonry structures could result hugely damaged if shaken forces. In order to avoid collapses and reduce structural damage, innovative retrof...
The objective of this review to be submitted in two independent parts, for steel frames and for RC frames, is to compare their structural performance with respect to the proposed N2-method, and so also of the consequent convenience of using pushover methodology for the seismic analysis of these structures. A preliminary investigation is presented on a pushover analysis used for the seismic perf...
