RISCase Study: Seismic Upgrade of a Masonry Bell Tower Using Glass Fiber-Reinforced Polymer Ties
Publisher: American Society of Civil Engineers
Abstract: In many cases masonry buildings present structural problems related to development of local mechanisms under seismic actions. The solution to this weakness has to be chosen taking into account several aspects if the ...
Axial Stress–Strain Model for FRCM Confinement of Masonry Columns
Publisher: ASCE
Abstract: Masonry columns often exhibit a lack of load-carrying capacity that is due to overloads and do not provide any ductility or dissipation capacity under seismic forces. Column confinement has been extensively studied as an ...
Numerical Investigation on the Influence of FRP Retrofit Layout and Geometry on the In-Plane Behavior of Masonry Walls
Publisher: American Society of Civil Engineers
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 ...
Assessment of Design Formulas for In-Plane FRP Strengthening of Masonry Walls
Publisher: American Society of Civil Engineers
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 ...
Nonlinear Analyses of Tuff Masonry Walls Strengthened with Cementitious Matrix-Grid Composites
Publisher: American Society of Civil Engineers
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 ...
Structural Upgrade Using Basalt Fibers for Concrete Confinement
Publisher: American Society of Civil Engineers
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 ...
Discussion of “Nonlinear Uniaxial Material Model for Reinforcing Steel Bars” by Sashi K. Kunnath, YeongAe Heo, and Jon F. Mohle
Publisher: American Society of Civil Engineers
Out-of-Plane Retrofit of Masonry with Fiber-Reinforced Polymer and Fiber-Reinforced Cementitious Matrix Systems: Normalized Interaction Diagrams and Effects on Mechanisms Activation
Publisher: ASCE
Abstract: Nowadays retrofitting and strengthening of masonry buildings are important challenges for structural engineering to ensure the structural safety under seismic or exceptional loads. This paper aims to clarify the effects ...
Methodology for Assessing the Performance of RC Structures with Breakaway Infill Walls under Tsunami Inundation
Publisher: ASCE
Abstract: The increasing attention of governments and insurance companies toward the evaluation of tsunamis’ impacts on coastal communities led to a renewed interest in assessing the behavior of existing buildings under onshore ...
Analytical Evaluation of FRP Wrapping Effectiveness in Restraining Reinforcement Bar Buckling
Publisher: American Society of Civil Engineers
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 ...
