Nine restrained T-beams were tested in a study of the negative moment region shear strength of lightly reinforced concrete T-beams. Variables included the longitudinal reinforcement ratio p, (0.47 percent and 0. 70 percent) and the nominal stirrup strength (0 to 84 psi [0 to 0.60 MPa]). The test results are compared with the shear provisions of "Building Code Requirements for Reinforced Concret...

In this paper, an experimental study is presented on the influence of PET warping on shear performance, such as diagonal shear cracking load, peak load, and energy dissipation of RC columns with stirrup corrosion before strengthening. The experimental program involved an electrochemical process to accelerate the migration of chlorides from an external electrolyte into the tested columns, a wett...

Reinforced concrete (RC) column is an important load-bearing component in building structures. In order to study the blast resistance of RC columns, numerical simulation model was verified based on field test data, and ANSYS/LS-DYNA 2020R2 software used expand working conditions. The sensitivity analysis method grey relation degree effects factors, such as diameter longitudinal reinforcement, n...

Introduction Most lower limb orthoses cannot be used without footwear. Occasionally, barefoot walking by patients fitted with orthoses may be necessary due to economic circumstances, to satisfy the dictates of religion, or for other reasons, such as the discomfort of conventional footwear in hot and humid climates. Invariably a boot or shoe is the foundation for an orthosis, with a stirrup rive...

Ogston & Stanier (1950, 1951, 1952) have referred to measurements made with a Couette viscosimeter. Since this viscosimeter can be constructed almost wholly in an ordinary laboratory workshop, and since it has proved to be convenient and accurate in CONSTRUCTION Drive. A type RQ synchronous motor, 73 rev./ min. (Drayton Regulator and IIistrument Co. Ltd.) is coupled by a stirrup coupling to the...

The CRB600H reinforcement is a new type of cold-rolled ribbed steel bar, which has the advantages green and low carbon, stable quality, saving precious metal resources so on. In order to study axial compression performance short concrete columns with stirrups, finite element analysis model high-strength reinforced stub was established by using ABAQUS, accuracy verified literature experiments. e...

A standard skeletal traction technique was applied to each major segment of the appendicular skeleton of ten fresh dog cadavers. Opposition points and anchorage points for the application of traction were determined for each skeletal segment. Traction was exerted by means of a micrometric traction stand, connected to the limb by bands or a stirrup. Traction was applied to the antebrachium and t...
