The model 302, and a series of similar models for special service types, is built upon a rectangular steel base-plate on which are mounted the ringer unit, the induction coil, a metal container enclosing two capacitors, and a connector terminal plate. The base was supported by four felt- or leather-covered triangular feet attached under each ...
In the past two decades the steel plate shear wall (SPSW), also known as the steel plate wall (SPW), has been used in a number of buildings in Japan and North America as part of the lateral force resisting system. In earlier days, SPSWs were treated like vertically oriented plate girders and design procedures tended to be very conservative.
The software includes full support for British, European and South African design codes, with some modules also supporting North American, Australian, New Zealand, Russian and selected Asian design codes. [6] PROKON appears on the Hong Kong Building Department list of pre-accepted computer programs for use in Hong Kong. [7]
Each assembly has two parallel steel plates joined by welded stringers or tie bars. The assemblies are then moved to the job site and placed with a crane. Finally, the space between the plate walls is filled with concrete. [1] The method provides excellent strength because the steel is on the outside, where tensile forces are often greatest.

A plate is a structural element which is characterized by a three-dimensional solid whose thickness is very small when compared with other dimensions. [ 1 ] The effects of the loads that are expected to be applied on it only generate stresses whose resultants are, in practical terms, exclusively normal to the element's thickness.
The importance of the high-precision surface plate was first recognised by Henry Maudslay around 1800. He originated the systems of scraping a cast-iron plate to flatness, rubbing marking blue between pairs of plates to highlight imperfections, and of working plates in sets of three to guarantee flatness by avoiding matching concave and convex ...
On certified steels, the plates are marked with the grade and a preceding "AB/", e.g. AB/A etc. [3] Yield point for all ordinary-strength ABS steels is specified as 34,000 psi (235 MPa ), except for ABS A in thicknesses of greater than 1 inch (25 mm) which has yield strength of 32,000 psi (225 MPa), and cold flange rolled sections, which have ...
