This paper presents the shear behavior of lightweight concrete beams
without shear reinforcement produced by scoria aggregates. A total of nine
beams were tested under four-point loads, including three lightweight
concrete beams without steel fibers and six steel fiber reinforced
lightweight concrete beams.
The aim of this study is to determine strength of adhesive single-lap joints of
Aluminum alloys which are widely used in geometric applications. It was investigated to
define the influence of overlap length and surface roughness value on shear stre
ngth of
achieved adhesive joints. It was used Epoxy and Acrylic adhesives to prepare adhesive
joints and all the specimens were subjected to axial tensile tests and the results are
presented as a comparison.
Results of those tests showed that shear strength increased with increasing each of
overlap length and surface roughness of adherends and Acrelicadhesiveproduced4better
results according to failure mode of tested samples.
Clayey expansive soils are fine grained soil with a low strength. Its
swelling potential and shear strength are significantly affected by
the water content.
This research aims to study the effect of the initial water content
on both shear strength and the required displacement to reach the
maximum strength.
