Question

Which of the following statement is correct?

(a) beams are termed as fixed beams when end condition do not carry end moments

(b) beams are termed as simply supported beams when ends are rigidly connected to other members

(c) beams are termed as fixed beams when ends are rigidly connected to other members

(d) beams are termed as continuous beams when they do not extend across more than two support

I had been asked this question during an interview for a job.

Query is from Introduction to Beams topic in section Design of Beams of Design of Steel Structures

Answer 1

Right option is (c) beams are termed as fixed beams when ends are rigidly connected to other members

The explanation: Beams may be termed as simply supported beams when end condition do not carry any end moments from any continuity developed by connection.  A beam is called continuous beam when it extends continuously across more than two supports. A fixed beam has its ends rigidly connected to other members, so that moments can be carried across the connection.
