Strengthening unreinforced masonry walls using natural hemp

This paper presents an experimental setup to study the effectiveness of using natural hemp fibers for enhancing the out of plane flexural capacity of unreinforced masonry walls. Wall specimens are constructed using normal-weight hollow concrete masonry units, and then hemp fiber fabrics are externally applied for strengthening.

Evaluation of seismic displacement demand for unreinforced

unreinforced brick masonry (URM) structures, unreinforced adobe or block masonry structures and stone masonry structures. The poor performance of stone masonry walls in the Himalayan belt has been reported (Ali et al., 2013) and experimental and analytical studies on stone masonry walls are also available (Ahmad, Ali, Ashraf, Alam, & Naeem, 2012).

Unreinforced Masonry Wall Stresses

Shear walls are Plain Unreinforced Masonry. Interior non load bearing are unreinforced. Chicagoland area. We detail #4 Dowels @ 48" OC for the required mechanical connection to the foundation per IBC 2009. We didn't do this up until IBC 2009. No mechanical connection hasn't created any problems. Concrete masonry is concrete, foundation wall is ...

Unreinforced Masonry - How is Unreinforced Masonry abbreviated?

Looking for abbreviations of URM? It is Unreinforced Masonry. Unreinforced Masonry listed as URM ... of Prefabricated Concrete Walls on Masonry Structures: Shaking ...


Masonry structures comprise a significant portion of the buildings worldwide most of which are constructed with unreinforced masonry blocks. Unreinforced masonry structures have low resistance to out of plane blast loading due to their low flexural capacity and as a result will experience brittle failure modes.
