Wind-Moment Frame: a type of structural frame that is simpler to design but less resistant to horizontal forces than a portal frame. and the rebar closest to that face, which is encased in the concrete. Standard MGP grades are MGP10 (normally non-structural timber), MGP12 (structural timber) and MGP15 (more expensive structural timber). Truss: a structure composed of straight members connected in triangles, requiring no bending resistance in principle as the member forces are purely axial. N25, N32 and N40 concrete is used for industrial and commercial slabs depending on the loads, surface strength and flexural capacity required.

It often spans from one floor level up to the next. Your email address will not be published. The strip footings are normally 300mm wide and spaced at up to 6m centres. PT slabs are often used for parking garages, podiums, and high-rise multifamily construction. When you don’t work in the industry every day, structural and civil engineering terminologies can be confusing. What it is not: Carnegie Mellon University. Learn. What it is not: Physical training–push-ups, pull-ups, sprints, etc. Live Load: another term for Imposed Load. the weight of people and furniture; or wind forces on exterior walls). Flashing is the sheet metal that is bent and placed by roofers to seal a roof at the cut ends of roof sheeting. Needle Beam: a short length of timber or steel that is inserted through a hole in a wall, with props at each end to enable the wall to be supported while work takes place beneath. the strength of the concrete will be less than specified and ordered. All rights reserved. CMU construction is used in a variety of low-rise applications, particularly when durability, acoustic separation, and/or fire separation is a concern. We have an article on Abelflex that you might like to read. Find out more about soil classifications in this article. Have a great day! All structural elements deflect to some degree – even if they are strong enough to carry the loads safely – but part of good structural design involves predicting the amount of deflection and coordinating with the architect to ensure that it does not cause non-safety-related issues (like cracking, sticking doors, leaking windows, etc.). WGI is a dynamic organization with opportunities nationwide for engineers, land surveyors, landscape architects, environmental scientists, and architects. What it is not: A defensive play in basketball. Ask your engineer. MGP10 timber is used for non-loadbearing walls. A stud is normally one of many vertical pieces of timber or steel used in a wall frame to support the roof and internal and external cladding (the wall). A stringer is the structural beam that supports the treads of a stair. A twisting force where two opposing forces rotate in opposite directions. The strength of the waffle slab comes from reinforcement in the bottom of the internal strip footings and the 300mm wide perimeter edge beam (bottom reinforcement) and mesh reinforcement in the slab (top reinforcement) . How to Set Up Your Website PortfolioA free guide to hosting your own website potfolio. Span: the distance between the centres of supports for a beam or truss. it might be used to keep a pathway (10mm) away from a house slab or to create a gap around a pipe that passes through a footing. A permanent change in a material due to stress. Commonly these are made from concrete either cast in-situ or pre-cast, or engineering bricks. A body that supports a load and will resist external forces without changing its shape, except for the elasticity of the material used. Required fields are marked *, © A compression force applied to a material in opposite directions that slide past each other across a perpendicular plane. I liken the test to filling up a bucket of water and watching to see if the water level drops. These are the main reasons we prefer raft slabs over waffle slabs. CFW stands for continuous fillet weld. You can get galvanised iron strap from your local hardware shop in a roll. Typical strap dimensions are 30mm x 0.8mm. He has also led the structural design of large-scale office buildings, warehouses, hotels, multifamily developments, and horizontal infrastructure. Flexible Design provides the framework for anticipating disruptive trends & impacts. Depending on the location of your building, the DuraGal might need extra corrosion protection. Columns are designed to resist compression, but it is also produced in bending of beams. Extra strength is achieved by increasing the height of the slab above the ground with resultant deeper internal strip footings and edge beams. Formwork often comprises props, scaffolding, joists, bearers and form boards. We look forward to meeting you soon. Structures are usually intended to resist movement, so the effect of the force is to change the shape of the structure, causing deflection. We use a full-strength butt weld when maintaining the full strength of the parent steel is critical. Meet our Awesome Associate Maria Ballester, an Engineer Intern from our Transportation team in Miami, Florida. We prefer using MGP12 softwood but sometimes use MGP15 for heavy loads. Below is a quick reference guide of commonly used terms so next time your engineer drops one of them on you, you’ll be ready. Roofs and bridges are applications for which trusses are well suited. (So tempted to put a picture of Brad Pitt here!) Learn vocabulary, terms, and more with flashcards, games, and other study tools. Although, for some, the terms civil engineering and structural engineering may look similar, the truth is, they are quite different from each other. What did we miss? Now you just have to find it and repair it. We prefer sewer flood tests over camera inspections of pipework as an initial test. Structure: a system of components devised to support loads and/or resist forces. WGI is providing ongoing services for multiple projects at the Ala Moana Center, located between Honolulu Harbor and Waikiki on the island of Oahu in Hawaii. Thinking about using Cross Laminated Timer for your next building project? Each material will have a limiting strain at which interatomic forces can no longer resist the applied stress, and either plastic deformation or rupture occurs. The weld should be a continuous (not-ending) fillet weld.
