Prestressed Steel Rebars:These are steel bars thar are used as strand or tendons. In this type of rebars, strand that are made of multiple wires are employed into concrete to perform prestressing action. These wire strands are cold deformed and consists of high tensile strength in the range of...
The ECPH Encyclopedia of Mining and Metallurgy Xie Liang 1 Accesses Steel rope for mine includes mine hoisting steel rope, mine freight ropeway steel rope, endless rope haulage steel rope, etc. The steel rope for mine used in Chinese mines mainly refers to the mine hoisting steel rope....

This paper evaluates the effects of severity of Torsional Irregularity (TI) and In-plane Discontinuity in Vertical Lateral force-resisting element Irregularity (IDVLI) together with seismic strength of the building on the progressive collapse potential of steel Special Moment-Resisting Frames (steel SM...
They are called a "general" case and "lateral torsional buckling curves for rolled sections or equivalent welded sections".At first are drown the drawings of these two type curves, because they are not given in EC3.The comparison is made according to the type of the cross-section, not ...
The problem to be solved is the quantitative identification of changes in the metallic cross-section of a rope. Keywords: non-destructive testing; magnetic sensors; residual magnetic field; steel wire rope1. Introduction 1.1. The Current State of Steel Wire Rope Diagnostics The first steel wire ...
The workability of fabricated fresh LWC was examined firstly with a slump cone and then molded with laboratory steel molds. The prepared specimens were demolded after 1 day of casting and water-cured with 100% relative humidity and a temperature of 20 ± 2 °C until the testing age; the ...
When dealing with heavy loads, it’s common to employ steel sections for the construction of beams. What are Beam End Conditions? Beam end conditions refer to how a beam is supported or restrained at its extremities. These conditions significantly influence the beam’s behavior under loads. Comm...
All the welding equipment and techniques we see today started during the Industrial Revolution. Since then, the welding process has progressed significantly. Now, different types of welding processes are used depending on factors such as: Type of metal welded - aluminum, copper, steel etc. ...
At one time this inspection requirement in steel pressure vessels was very important, but today it is mainly of historical interest. The rivet itself can develop transverse cracks between head and shank and these can be detected by testing from the rivet head, as on bolts (Section 22.4). Figu...
