Parameters affecting diagonal cracking behavior of reinforced concrete deep beams
Engineering structures, 2019In this study, an experimental study is performed to investigate the effects of section height ( h ), ratio of shear span to effective depth ( a / d ) and compressive strength of concrete ( f c ' ) parameters on diagonal cracking and crack width behavior

Tests were carried out on deep beams of steel and concrete. The distribution of the horizontal stresses for each test has been plotted and the expected magnitude at different points on a section were calculated. A theory based on the theory of elasticity, both for steel and concrete, and ultimate load for the concrete has been developed.

Deep concrete beams are the structural members that have different behaviors compared with normal beams. The high depth of these beams has made them favorable for placing the openings, which results in decreased load bearing capacity. This study utilizes

Shear strength of reinforced concrete deep beams with web openings
, 2020This study reports the test results for 24 reinforced concrete deep beams with square web openings. The main variables that are studied are the compressive strength of the concrete, the size of the openings, and the parameter for horizontal stirrups. The

A propped deep beam with opening is considered. This scenario has been the subject of past fib bulletins on strut and-tie modelling. The deep beam has height 4 m and span 11 m. The bottom left-hand corner is supported by a force 3000 kN and the right-hand edge is fixed to an adjacent shear wall. The deep beam is loaded on top by a point load 5000 kN at

Beaming Daylight Into Deep Rooms
Batiment International, Building Research and Practice, 1985Among the options of reducing energy consumption by artificial lighting in buildings is the effective use of natural lighting. By using direct-beam radiation from the sun, deeper light penetration and higher illuminance levels can be achieved in buildings that are predominantly used in the daytime.

Comparative analysis of deep beams
Computers & Structures, 1992Abstract The characteristic behaviour and mechanism of load transfer of deep beams are studied employing the eight-noded isoparametric finite element considering the effect of reinforcements. The authors' generalized formulation is specialized to ignore the reinforcement to apply in a problem solved earlier by other investigators with a view to ...

Deep nulling by means of multiple-beam recombination
Applied Optics, 2003Direct detection of exoplanets is possible by use of a technique called nulling interferometry, which is based on destructive interference of light of the bright object and constructive interference of the faint object. In the infrared wavelength region, this implies that light of a star must be attenuated by a certain factor, the so-called rejection ...
