Part of the structural engineer’s responsibilities is to prepare the project specifications including all building materials and applicable standards and provision to comply with. There are many types of building materials used in construction such as Concrete, Steel, Wood and Masonry. Wood, cement, aggregates, metals, bricks, concrete, clay are the most common type of building material used in construction. It has similar structural properties to steel, although its strength varies significantly. [...] with carbon-rich structural materials (straw, sawdust, [...] shredded particles etc), the focus is not so much on the direct nutrient effect but rather on the universal use as a material for improving the quality of the soil (humus substitute) and substrate in the various areas of … Steel is weak in fires, and must be protected in most buildings. Thank you for telling me that steel possesses an excellent strength capacity when it comes to tension and compression. Steel is used extremely widely in all types of structures, due to its relatively low cost, high strength-to-weight ratio and speed of construction. Each material has different properties such as weight, strength, durability and cost which makes it suitable for certain types of applications. Combined with steel rebar, reinforced concrete is stronger and more suitable for a wide range of structures such as tall multi-story buildings, bridges, roads, tunnels and so many other applications. Load bearing masonry walls can be stacked up on top of one another to build multi-story buildings. Stainless steel is an iron-carbon alloy with a minimum of 10.5% chromium content. It’s interesting that steel doesn’t take time to install and can be installed anywhere. Interested in taking your structural engineering basics knowledge to the next level? Building materials can generally be divided into two categories: Natural building materials such as stone and wood, and Man-made building materials such as concrete and steel. In industrialised countries, nearly all concrete used in construction is reinforced concrete. Corrosion resistance is excellent due to a thin surface layer of aluminium oxide that forms when the metal is exposed to air, effectively preventing further oxidation. Your email address will not be published. In a wood framed house, the foundations and basement walls are usually constructed with reinforced concrete. High masonry structures require stabilisation against lateral loads from buttresses (as with the flying buttresses seen in many European medieval churches) or from windposts. These shapes can be welded together or connected using high-strength bolts to build structures capable of resisting large forces and deformations. It is a readily available and economically feasible natural resource with a light weight and highly machinable properties. Because of its high strength-to-weight ratio, it is ideal for structural framework of tall buildings and large industrial facilities. This is commonly used in the construction of walls and floors. The choice of materials for construction is based on cost and effectiveness to resisting the loads and stresses acting on the structure. The main nonmetallic structural materials are plastics, thermoplastic polymeric materials, ceramics, refractory materials, glass, rubber, and wood. There are different types of stainless steel, containing different proportions of iron, carbon, molybdenum, nickel. The most common material I use in the design of masonry structures is concrete block, with vertical steel reinforcing if required. Masonry has been used in structures for thousands of years, and can take the form of stone, brick or blockwork. Historically masonry was constructed with no mortar or with lime mortar. It takes up to 7 days for concrete to reach the majority of its strength and will need special attention to curing to avoid cracking or reduction in capacity. The mortar glues the blocks together, and also smooths out the interface between the blocks, avoiding localised point loads that might have led to cracking. Some building materials like cold rolled steel framing are considered modern methods of construction, over … The load on the first floor masonry wall is the accumulation of all the weight of the floors above it. For example, concrete is an excellent material for building foundations where the weight of the structure meets the ground. Timber is the oldest of structural materials, and though mainly supplanted by steel, masonry and concrete, it is still used in a significant number of buildings. The properties of concrete depend on the ratios used in the mix design. Thanks for the informative article! Your information will *never* be shared or sold to a 3rd party. The structural system typically consists of concrete floors supported on a combination of masonry and reinforced concrete walls depending on the number of floors and amount of load on the walls. The properties of timber are non-linear and very variable, depending on the quality, treatment of wood, and type of wood supplied. Grab our FREE Ultimate Guide to Structural Engineering Basics here. I’ll ask our chosen contractor if this material can be used for residential buildings. Therefore, the bottom floor wall must be stronger than the upper floor walls. Concrete has very favourable properties in fire – it is not adversely affected by fire until it reaches very high temperatures. ceramic, metal and polymer matrix), construction materials (eg.
