What we mean by Coupling Beam ?

Coupling BEAM Definition Coupling beam is an important member of the lateral force resisting system in a structure. Consequently It couples or combines the two independent systems like shear walls. WHY WE PROVIDE COUPLING BEAM ? For example, Let’s assume there are two buckets, one is completely filled with water whereas other is half filled. […]

Optimizing long-span girders can save scares resources.  The following are a few conceptual options to optimize girders.  Optimization for a real project requires careful evaluation of alternate options, considering  interdisciplinary aspects along with purely structural ones. 1  Moment diagram, stepped to reflect required resistance along girder 2  Steel girder with plates welded on top of […]

Design of stair case with central stringer beam

  Design of stair case with central stringer beam R.C.C. STAIRS • Reinforced concrete is perhaps the most suitable of all the said materials for the construction of stairs. • The various advantages of reinforced concrete stairs are given below – They have requisite fire resisting qualities to a great extent – They are durable […]
