depth and a width to accommodate an end of an I-beam having an upper and lower metal flange of about equal width and a central metal web connecting the flanges, and in the building a hard rubberlike elastomer spacer is disposed between the I-beam receptacles and an end of an I-beam. ...
Beam (1) of high performance fiber-reinforced concrete, characterized in that it comprises a first spar (2.1) comprising at least one core (3.1), having a flange (4.1) along one of the longitudinal edges of the core and, along its opposite edge, a tongue (5.1) nested in a groove (5.2...
Some of the factors affecting the deflection of the beam were examined experimentally. These factors include the cross-sectional areas of the beam and the number of SMA wires, the pre-strain of the SMA wire, the curing condition (in a water tank or in a standard fog-curing box), the ...
EFFECTIVE SHEAR STRENGTHENING OF CONCRETE BEAMS USING FRP SHEETS WITH BONDED ANCHORAGE A retrofitting technique has been developed that uses carbon fiber-reinforced polymer (CFRP) straps to increase the shear capacity of reinforced concrete beams. The vertical straps are not bonded to the beam but are...
The paper deals with the study of dominant frequencies of an Impact-Echo method response signal obtained from a reinforced concrete beam with a steel rod d... ?amárková, Kristyna,Z Chobola,?tefková, Daniela - 《Advanced Materials Research》 被引量: 7发表: 2014年 Discrete Element Modeling...
The RC beam specimens used in the experiment comprised of under-reinforced sections provided with sufficient amount of transverse reinforcements to allow for an overall flexural failure. The experimental impact responses of the RC beams were simulated with two-degree-of-freedom mass-spring-damper ...
Static and Fatigue Response of High Strength Fibre Reinforced Concrete Beam with FRP LaminatesIn recent years FRP stands as a better alternative to restore and upgrade deficient structures. The deficiency may be due to change in design ... JRJ Stephen,KM Vinod - 《Esrsa Publications》 被引量:...
The permeability and elastic modulus of mature cement paste cured at temperatures between 8 degrees C and 60 degrees C were measured using a previously described beam bending method. The permeability increases by two orders of magnitude over this range, with most of the increase occurring when the...
It is observed that the cohesive zone model is robust, accurate and able to model the crack growth in the concrete beam. The prediction of the crack path is close to the experimental results (up to 90%). The peak loads had approximately 7.7% difference compared with the previous ...
The objective of flexural strength is to determine the tension of concrete beams through the application of force to an unreinforced concrete beam in a bending state until it cracks, then flexural strength is calculated based on the amount of force required for the beam to crack [40]. It is...
