I am designing a footing on rock. It is 800 deep and projects 300 beyond the column face. There are references available for deep simply-supported and continuous beams, for example, page 706 "Reinforced Concrete Structures"; Park and Paulay.
Could someone provide me corresponding...
Ron,
Whatever you suggested is for sure one of the arbitrary and conservative methods. Assuming there is a 800 feet long parking structure with centre of rigidity located at centre point. The structure may be a flat slab or slab and beam construction. A rule of thumb is to have shrinkage strips...
There are many arbitrary rules for provision of shrinkage strips in concrete floors. I am looking for a rational method for calculating shrinkage strips spacing.
Talking of softwares, someone mentioned ETABS 8 nonlinear. I do not think it is available. The latest, perhaps, is V. 7.23. And believe me it is a pain to use. Has someone used it for a reasonably tall building?
Exactly, we have to confine the compression reinforcement and not the section. Besides, the compression reinforcement may be required only for critical segments of a span. For example, for simply-supported beams it may only be a limited length at midspan requiring compression reinforcement to...
compression reinforcement is sometimes provided in beams solely for the purpose of reducing time-delayed deformations due to creep and shrinkage of concrete. Does this reinforcement need be confined (with ties)?
What rules govern the termination points of such compression reinforcement?
