Conference Paper
Full-text available
Six simply supported deep beams were tested to show the influence of prestressing strand on the behavior of reinforced concrete deep beams. All tested beams have same gross sectional area (42000) mm2 , compressive strength (30) MPa, clear span length (1000) mm, longitudinal and vertical reinforcement and the strengthened beams are strengthening by...

In this experimental work, eight beams are casted and tested under two-point load in order to study the influence of geo-grid layers on the performance of reinforced concrete beams. The tested beams have same dimensions (100 × 200) mm, clear span length (1000) mm, compressive strength (f’c = 30) MPa and shear reinforcement (θ4@100 mm C/C). The test...
Article
Three steel beams were made-up and tested to study the effect of CFRP (Carbon Fiber Reinforced Polymer) laminates with and without end anchorage plates on the behavior of flexural strength of steel beams. Tested steel specimens are equal in clear span length, gross sectional area, and strengthened by intermediate stiffeners. Three types of specimen...

Now, using of geogrids as strengthening material are extend used, especially to enhancement of concrete elements as inter layers concrete applications, eight beams were tested to explain the effect of geogrid on the behavior of reinforced concrete beams. Beams tested had equal cross-sectional dimension (100 mm x 200 mm), compressive strength ( f’c...

Full-text available
Thirteen simply supported steel samples have been tested to explain the effects of strengthening steel beams using an external prestressing strand. The samples have the same cross-sectional dimensions and overall length. One steel beam without strengthening was taken as a reference, while the other twelve of them had been strengthening by two exter...

Six I-section steel beams had been fabricated and tested to understand the influence of the prestressing strand on the load-deflection behavior of steel beam. All tested beams are simply supported having the same cross-sectional area with clear span (2850) mm, five beams strengthened by two low relaxation seven-wire strands, while the sixth beam is...

Twelve self compacted concrete (SCC) T-section beams were design and tested to determine the effect of using SCC on the shear behavior under two concentrated loads. All beams have the same longitudinal steel ratio of (0.018823) and gross section area of (20000) mm 2. The tested beams were divided into two groups-with and without stirrups. The first...
Article
Full-text available
The beam on elastic foundation is a common technical problem in engineering and many solutions have been proposed in recent years. The key aspect in the design of flexible structural elements in contact with bearing soils is the way in which soil reaction, referred to qualitatively as soil's reactive pressure (p), is assumed or accounted for in ana...

Abstract. Seven steel beams were tested under one point load to investigate the effect of existence of external prestressing strands on the behavior of steel beams at yielding stage. All steel beams have the same gross area, overall length and the strengthened specimens are employed by two low relaxation strands. The steel beams are divided into tw...

Conference Paper
Seven simply supported steel beams were tested to explain the effect of strengthening by external prestressing strands. All of these beams have the same steel section; clear span length and six of them strengthening by two external prestressing strands at different locations. During the tests, it was found that the load deflection curves for tested...
