In this paper the influence of vertical component ground motion on performance an unreinforced masonry wall is analysed using sets one-component and two-component motions. The set motions represents actual seismicity L'Aquila, while investigated mimics experimental specimen with two unconnected external leaves a rubble core. model falls within mixed finite element method – discrete accounts for...

Unreinforced masonry (UM) is well known as a vulnerable structure against earthquakes. However, it remains popular structural system for low-rise residential housing in many high-seismicity areas, particularly developing regions due to its low cost and easy construction. In the present study, retrofitting strategy using locally available material, bamboo strips, was proposed. addition fast-grow...

By Timothy Phillips Vaughan, MS. Washington State University May 2010 Chair: David I. McLean This research evaluated the structural performance of reinforced masonry shear walls conforming to requirements given in the 2008 MSJC Building Code Requirements for Masonry Structures under cyclic lateral loading. Seismic design provisions in the 2008 MSJC provide prescriptive requirements for three di...

Abstract Two full-scale building specimens were tested on the shake-table at EUCENTRE Foundation laboratories in Pavia (Italy), to assess effectiveness of an innovative timber retrofit solution, within a comprehensive research campaign seismic vulnerability existing Dutch unreinforced masonry structures. The buildings represented end-unit two-storey terraced house typical North-Eastern Netherla...

This paper is aimed at proposing a strengthening method for improving the seismic performance of unreinforced masonry (URM) brick walls. What noteworthy regarding proposed technique low price and easy application polypropylene (PP) bands, which are widely used in packaging industry. Three half-scale specimens were tested under cyclic lateral loading simultaneously with imposing constant vertica...

Laboratory experimental data is often erroneous. This error is more apparent in data obtained from testing of anisotropic composite materials such as masonry wall panels. In this paper data colleted from the laboratory tests of masonry panels is presented. Methodologies for reducing (correcting) error in laboratory tested data are discussed. The concept of stiffness/strength corrector to model ...

This paper presents an experimental program dealing with the shear strengthening with FRP systems of URM walls built with concrete and clay units. Ten concrete and five clay masonry panels, strengthened with FRP composites in the form of laminates and rods, and stainless steel, were loaded along the wall diagonal to observe their shear performance. The dimension of the concrete masonry panels w...
