A sailor checks the outside diameter of a shear pin in the machinery repair shop aboard US aircraft carrier John C. Stennis. A shear pin is a mechanical detail designed to allow a specific outcome to occur once a predetermined force is applied. It can either function as a safeguard designed to break to protect other parts, or as a conditional ...
The last are used in concrete-steel composite structures as shear connectors. [6] Other uses include anchoring machines to poured concrete floors [ 7 ] and buildings to their concrete foundations. Various typically disposable aids, mainly of plastic, are produced to secure and align cast-in-place anchors prior to concrete placement.
For example, a footed pin head style anchor maybe more susceptible to edge distance than a hairpin style anchor. Or a splayed anchor does not have the same tensile/axial capacity with the equivalent anchor length (effective embedment is greater on a footed anchor than a splayed anchor of equivalent overall length, see figure 4).
A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel- reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving ( see below ).
foundation; bracing; If the joints are not rigid, they will "open up" and the frame will be unstable when subjected to loads. This is the pack of cards effect. Vertical loading results in the walls being pushed outwards. If the foundation cannot resist horizontal push, outward movement will occur and the frame will lose strength.
The 16 Divisions of construction, as defined by the Construction Specifications Institute (CSI)'s MasterFormat, is the most widely used standard for organizing specifications and other written information for commercial and institutional building projects in the U.S. and Canada.
Wall framing in house construction includes the vertical and horizontal members of exterior walls and interior partitions, both of bearing walls and non-bearing walls. . These stick members, referred to as studs, wall plates and lintels (sometimes called headers), serve as a nailing base for all covering material and support the upper floor platforms, which provide the lateral strength along a
The Construction Specifications Institute (CSI) is a United States national association of more than 6,000 construction industry professionals who are experts in building construction and the materials used therein. The institute is dedicated to improving the communication of construction information through a diversified membership base of ...
