In engineering, reliability, availability, maintainability and safety (RAMS) [1] [2] is used to characterize a product or system: Reliability: Ability to perform a specific function and may be given as design reliability or operational reliability; Availability: Ability to keep a functioning state in the given environment
A work method statement, sometimes referred to as a safe work method statement or SWMS or a safe work procedure, is a part of a workplace safety plan. [1] It is primarily used in construction to describe a document that gives specific instructions on how to safely perform a work related task, or operate a piece of plant or equipment.
The Wood–Armer method is a structural analysis method based on finite element analysis used to design the reinforcement for concrete slabs. [1] This method provides simple equations to design a concrete slab based on the output from a finite element analysis software.
Rams can extend and apply directed force much further than the arms of a spreader, making them ideal for reaching deep into crushed vehicle compartments. For example, a ram may be used to push away the dashboard to free a trapped occupant’s legs. There are many types and sizes of rams, including single-piston, dual-piston and telescopic rams.
To demolish bridges, hoe rams are typically used to remove the concrete road deck and piers, while hydraulic shears are used to remove the bridge's structural steel. Bridge demolition using explosives near Nieuwersluis, The Netherlands, 1920-1940. Fred Dibnah used a manual method of demolition to remove industrial chimneys in Great Britain. He ...
Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the work to be completed at ground level, negating the ...
Other manufacturers were thus compelled to use other terminology to describe the process such as shotcrete, pneumatic concrete, guncrete, etc. Shotcrete is an all-inclusive term for spraying concrete or mortar with either a dry or wet mix process. However, shotcrete may also sometimes be used to distinguish wet-mix from the dry-mix method.
