Why is beam used in buildings?
Answers
Answer:
Beams primarily carry vertical gravitational forces. They are also used to carry horizontal loads (e.g., loads due to an earthquake or wind or in tension to resist rafter thrust as a tie beam or (usually) compression as a collar beam). ... In light frame construction, joists may rest on beams.
Beams are horizontal structures that mainly resist loads. Traditionally, beams are a description of buildings. Beams carry vertical gravitational forces and also used to carry horizontal loads. The Primary horizontal beam connects columns Secondary horizontal Beam beam connects the primary beam. To construct the buildings or other structure, different kinds of beams are used. Based on the different conditions, there are many types of beams such as based on geometry, based on support conditions, based on cross-section shapes.etc.
