| | Summary: |
| | The paper analyzes the results of reinforced concrete flat slabs, using
different methods based on the theory of elasticity and theory of plasticity. Were
considered three methods: stripe method, method according to Hillerborg and Wiesinger
and Yield Line theory. The stripe method based on the theory of elasticity and is one of
the most commonly used methods for calculation flat slabs, which are recommended by
many regulations for calculation reinforced concrete structures. This paper also
presents two methods based on the theory of plasticity, the method according to
Hillerborg and Wiesinger - lower bound and Yield Line theory - upper bound, which
uses a solutions of Johansen. Solutions obtained by these methods define limits interval
of critical load. Review the basic theoretical hypothesis of all these methods and their
application to flat slabs. Conducted calculation according to Eurocode 2 with a regular
arrangement of pillars, analyzed the results and commented differences that occur as a
result of the adoption of various hypothesis. |
