how much do real estate agentsmake
Truss. In architecture, a structural framework of wood or metal based on a triangular system, used to span, reinforce, or support walls, ceilings, piers or beams.

What construction device is used to span spaces or make enlarged openings?

Lintel - It is a structural horizontal block that spans the space or opening between two vertical supports.

What is the triangular piece of wall above the entablature in Greek architecture?


The pediment was the crowning feature of the Greek temple front. The triangular wall surface of the pediment, called the tympanum, rested on an entablature (a composite band of horizontal moldings) carried over the columns.

What is the triangular upper part of the front of a building in classical style typically surmounting a portico of columns

A pediment is the triangular upper part of the front of a building in classical style, typically surmounting a portico of columns.

What are the triangular shapes used in architecture?

Triangles are known as the sturdiest figure in the architecture world. Architects commonly use these shapes to construct their buildings. The inequalities help prove that the shape is actually valid and can be build without causing problems.

Where is steel roof truss used?

It is a type of steel truss that is commonly used in steel buildings, where support to roofs, the floors and internal loading such as services and suspended ceilings, are readily provided. Its advantages: Long span that wood timbers can not support. Lightweight and strong.

What is the steel truss method of construction?

Trusses typically contain of five or more triangular units, using straight components connected at joints, or nodes. Trusses can be made of different materials and take a variety of architectural shapes. Many structures rely on steel trusses for enhanced strength, durability, and reliability.

Frequently Asked Questions

What are steel trusses used for?

Trusses are used in a broad range of buildings, mainly where there is a requirement for very long spans, such as in airport terminals, aircraft hangers, sports stadia roofs, auditoriums and other leisure buildings. Trusses are also used to carry heavy loads and are sometimes used as transfer structures.

Are trusses part of framing?

Trusses manufactured with dry lumber do not warp, twist, creating a framing system that is easy to properly place and sheath. By eliminating interior bearing walls, trusses also save the cost of interior foundation walls, interior partition top plates and headers.

What can trusses be made out of?

Truss, in engineering, a structural member usually fabricated from straight pieces of metal or timber to form a series of triangles lying in a single plane.

Which type of construction would use lightweight wood trusses?

Type 5 construction

Type 5 construction is found in many modern homes. The walls and roofs are made of combustible materials–most commonly wood. If the walls are wood-framed, the roof usually is as well. Rooftops are ceramic tile or asphalt shingles placed over lightweight trusses and OSB.


What is the difference between conventional and lightweight construction?

Lightweight Construction

Unlike conventional construction, lightweight truss construction does not derive strength from size. Strength is obtained from multiple members that are in compression and tension.

How can lightweight or engineered trusses react under fire conditions?

Expect imminent collapse once lightweight truss roofs or floors are involved in a fire (Klaene and Sanders 2000). If possible, avoid cutting the truss chords when cutting holes for roof ventilation. Cuts can weaken the roof.

What are the 4 types of lightweight construction?

This section will focus on the four major types of lightweight roof construction: panelized, metal gusset plate trusses, open web construction, and wooden "I" beams.

  • Why use steel trusses?
    • In contrast to wood, steel is also fire- and pest-resistant and won't rot. It requires little maintenance over time and is 100% recyclable at the end of its lifespan. Steel trusses can also withstand strong winds, heavy snow loads, and intense pressure. They can be fabricated to withstand high wind uplift, as well.

  • Which of the following relate to lightweight truss construction?
    • ... trusses are sometimes categorized as: Light frame trusses. Heavy timber trusses. Split Ring Trusses ... truss joists are used in floor construction? Four: Up, 

  • What type of construction used steel trusses
    • Pratt trusses are commonly used in long span buildings which range from 20 to 100 m in span. In a conventional Pratt truss, diagonal members are in tension for
