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 ...

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...

We present the results of experimental studies and modelling evaluation bearing capacity hollow 3D-printed walls with printed shell performing functions. The was experimentally assessed depending on ratio void areas casting layers in wall structure. It established that case central loading, a can serve as similar to traditional types masonry construction without filling voids structural concret...

Understanding the out-of-plane behavior of unreinforced masonry walls is crucial in seismic assessment existing buildings. Here, dynamic response a vertical spanning strip wall, connected to flexible diaphragm at top, investigated. Despite simplicity model, two rocking rigid bodies elastically restrained highly nonlinear. This due different phenomena: when motion system may assume configuration...
