Beam column意思

"Beam column" is a structural engineering term that refers to a member or element that combines the functions of a beam and a column. This term is used when a structural element is subjected to both axial compression (like a column) and bending (like a beam).

In buildings, beam columns are commonly found in frames or as part of a load-bearing wall system. They are designed to resist both the gravitational loads (due to their own weight and the weight of the structures above) and the horizontal loads (such as wind or seismic forces).

Beam columns can be made of various materials, including steel, concrete, wood, or a combination of these materials. The design of beam columns requires careful consideration of the material properties, loading conditions, and the expected behavior of the structure during an earthquake or other dynamic events.

In steel structures, for example, a beam column may be a single member that is designed to carry both axial and bending loads, or it may be a composite member consisting of a beam and a column connected together. In concrete structures, the concept of a beam column is often applied to the design of reinforced concrete frames, where the columns are designed to resist axial compression and the beams are designed to resist bending.

The design of beam columns is governed by various codes and standards, such as the International Building Code (IBC) and the American Society of Civil Engineers (ASCE) 7 Standard. These codes provide guidelines for the design of beam columns to ensure that they can safely support the loads they are designed to carry without failing under normal or extreme conditions.
