This paper shows the efficiency of the vertical and annular post-compression for wind and seismic structural behavior improvement of slender masonry chimney. For this aim a case study approach regarding an old masonry chimney is used. The paper shows the safety analysis and the safety improvement obtained applying at the same time a vertical and an annular masonry post-compression. The vertical post-compression is obtained through the post-tensioning of twenty-four vertical stainless-steel thin bars. These bars are connected to the chimney masonry only at the basement and at the top. They are placed inside the central void and horizontally distributed along a circumference near the inside face of the masonry, but without to touch it. The annular post-compression is obtained post-tensioning forty-five annular aramidica “not twisted” cables, placed and glued (after the post-tensioning) inside horizontal mortar joints of the more external masonry brick layer.

Strength And Ductility

In this paper, experimental and numerical results of a research project about the structural behavior of strengthened masonry are presented and discussed. The aim of the research is to study the in-plane shear behavior of an old masonry wall with an opening in the arch form, reinforced with a pioneering system of 3D pre-tensioned stainless steel ties. The masonry wall was in-plane loaded until first cracking appeared, then it was reinforced and re-loaded until failure. The experimental results have highlighted the benefits of the reinforcing method adopted, especially to provide an increasing in terms of both strength and ductility. Numerical modeling of the masonry wall behavior was accomplished by using non-linear finite-element methods generally adopted for reinforced concrete elements.

Based on the existing test results of single shear bolted connection fabricated with cold-formed ferritic stainless steel, in this study, the experiment for double shear bolted connections with bolt arrangements(1×2, 2×2) and end distance parallel to the loading direction as main variables has been performed. Specimens were planed with a constant dimension of edge distance perpendicular to the loading direction, bolt diameter, pitch and gauge. Ultimate strength and fracture mode obtained from test results were compared with those predicted by current American and Japan design codes such as AISI and AIJ.
