Hollow concrete block for masonry walls and masonry wall with concrete blocks of this typeJAN ALBERT DOUTERLOIGNE
The specification describes pre-split concrete masonry units (CMU) with a splitter guide pattern in the top surface of the masonry unit. The process described in Us 5,249,950 & US 5,062,610 is modified by forming a splitting pattern on the top, or "lips-up", surface of the pre-split...
Impact tests using drop-weight pendulum on nine 1.2-m-high full-scale concrete masonry block walls were conducted to investigate the out-of-plane impact behavior of unreinforced masonry (URM) walls externally strengthened with carbon-fiber-reinforced polymer (CFRP) composites. Three strengthening scheme...

The exterior walls of conventional structures are often constructed using concrete masonry units (CMUs), commonly called concrete blocks. A series of experiments was conducted at the U.S. Army Engineer Research and Development Center to determine the response of a one-way14-scale CMU wall to the...
This three-hinged arch mechanism allowed the walls to develop large in-plane compressive forces, which subsequently increased their out-of-plane resistances and prevented flying debris due to increased friction forces between the masonry courses. Comparing the observed strength of the arched walls to ...

EFFECTS OF MASONRY WALLS ON THE SEISMIC RISK OF REINFORCED CONCRETE FRAME BUILDINGS The observation of building damage after earthquakes has shown that the contribution to the seismic performance of concrete frame buildings from infill walls is significant and should not be ignored. Despite the added ...
