Study of alternative geometry of hollow self-compacting concrete masonry blocks
(2020-01-01)
To evaluate the geometrical influence of new types of hollow concrete blocks, six different geometries were investigated using self-consolidating concrete to fabricate the blocks. The cell shapes studied were circular, ...
High-Strength Concrete Masonry Walls under Concentric and Eccentric Loadings
(Asce-amer Soc Civil Engineers, 2018-06-01)
Masonry walls and columns are common structural members that typically resist compressive loads, with a number of such members being required to resist combined axial load and out-of-plane bending due to direct out-of-plane ...
On the compressive strength prediction for concrete masonry prisms
(SPRINGER, 2010)
The results of a combined experimental program and numerical modeling program to evaluate the behavior of ungrouted hollow concrete blocks prisms under uniaxial compression are addressed. In the numerical program, three ...
