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...

The predictability of masonry arch bridges and their behaviour is widely considered doubtful due to the lack of knowledge about the conditions of a given masonry arch bridge. The assessment methods for masonry arch bridges are MEXE, ARCHIE, RING and Frame Analysis Method. The material properties of the masonry and fill material are extremely difficult to determine accurately. Consequently, it i...

Close to reality computation of the serviceability and load-carrying capacity of old masonry arch bridges for rising live loads is a current problem. In Germany many of such roadand railway bridges exist. Some of the most important features for applicable numerical evaluation of masonry arch bridges are a realistic structural model (very often three dimensional models are necessary), the consid...

This paper presents part of a research into the small scale modelling of masonry. Small scale testing of masonry has been carried out by many authors, but few have attempted a systematic determination of the parameters that affect masonry at a small scale. The effect of increasing mortar strength and different sand gradings under compression were investigated. The results show masonry strength ...

The mechanical response of stone masonry depends on the properties of the components and also on the typology created by the stone units and the mortar joints. While the influence of the component strength on masonry is relatively well studied, mainly due to the difficulty of varying the masonry typology systematically, few research studies have been devoted to its influence on masonry properti...

When testing multi-storey structures, most testing facilities require the testing of a reduced-scale model. A literature review on tests of scaled masonry structural components revealed that scaling of masonry was rather challenging and often significant differences in stiffness, strength and failure mechanisms between the different sized masonry were reported. This paper addresses the scaling ...

Brick is one of the most common masonry units as a building material due to its properties. Many attempts have been made to incorporate wastes into the production of bricks, for examples, rubber, limestone dust, wood sawdust, processed waste tea, fly ash, polystyrene and sludge. Recycling such wastes by incorporating them into building materials is a practical solution for pollution problem. Th...

Abstract An ultrasonic technique has been experimented for non destructive testing of building structures. The Through Transmission Technique has been applied, processing the wave incident on a grid of detecting probes after it has been transmitted through a trachite stone masonry with an inside cavity. Several parameters associated with acoustic waves propagating through the structure have bee...

Since the establishment of ASTM standard C91, masonry cement mortars have become widely used for masonry construction in low to moderate seismic regions. However, the Masonry Standards Joint Committee Code prohibits the use of masonry cement mortars in lateral force resisting systems for structures that fall into Seismic Design Categories D, E, and F. The general objective of this study is to e...
