Applications of Concrete Framing Systems

A concrete frame is a structure formed by the interconnection of beams and columns to form a structural network. In simple terms, it is the basic skeletal structure of a building or any construction. The concrete framing structure is built on a concrete foundation that forms the base of the entire structure. The concrete frame system is built to support floors, roofs, walls, beams, rafters, joists, etc.

Question

The rigid frame shown is unbraced. The members are oriented so that bending is about the strong axis.
Support conditions in the direction perpendicular to the plane of the frame are such that Ky = 1.0. The beams
are W410 x 85, and the columns are W250 x 89. A992 steel is used, Fy=345 mPa. The axial compressive dead
load is 750 kN and the axial compressive live load is 900 kN. Use the AISC alignment chart or Magdy I. Salama
