Bolt banging occurs in buildings when bolted joints slip into "bearing under load", thus causing a loud and potentially frightening noise resembling a rifle shot that is not, however, of structural significance and does not pose any threat to occupants. A bolted joint between two elements may act as a bearing-type joint, or a friction joint.
A load case is a combination of different types of loads with safety factors applied to them. A structure is checked for strength and serviceability against all the load cases it is likely to experience during its lifetime. Typical load cases for design for strength (ultimate load cases; ULS) are: 1.2 x Dead Load + 1.6 x Live Load
A bearing surface in mechanical engineering is the area of contact between two objects. It usually is used in reference to bolted joints and bearings, but can be applied to a wide variety of engineering applications. The choice of bearing surface depends on the application, load, speed, and operating conditions, and the design must be able to ...
Slip-critical joint, from structural engineering, is a type of bolted structural steel connection which relies on friction between the two connected elements rather than bolt shear or bolt bearing to join two structural elements.
Internal stress to a bearing through application of negative clearance is known as bearing preloading. Advantages of preloading include the following: maintain axial and radial position for accurate displacements of angular movements; increase bearing rigidity; prevent sliding or gyroscope-like movements, especially with high acceleration or ...
Anatomy of a plate girder. Generally, the depth of the girder is no less than 1 ⁄ 15 the span, and for a given load bearing capacity, a depth of around 1 ⁄ 12 the span minimizes the weight of the girder. Stresses on the flanges near the centre of the span are greater than near the end of the span, so the top and bottom flange plates are ...
Diagram of double tee beam. A double tee or double-T beam is a load-bearing structure that resembles two T-beams connected to each other side by side. The strong bond of the flange (horizontal section) and the two webs (vertical members, also known as stems) creates a structure that is capable of withstanding high loads while having a long span.
Case of two plates with a single overlap and one row of bolts. Dimensions used to design a bolted connection according to the Eurocode 3 standard. In a bolted connection, the role of the bolts is normally to press one parts on the other; the adherence is opposed to the tangent forces and prevents the parts from sliding apart. In some cases ...
