Failure of a Section of a Building
In a given section the program determines the following variables:
- maximum tensile strain
- maximum gradient
- maximum relative deflection
- relative gradient between input points of a building
Evaluation of the analyzed section is left to the user - the following tables list the recommended ultimate values of relative rotation and deflection.
Type of structure | Type of damage | Ultimate relative gradient | ||||
Skempton | Meyerhof | Polshin a Tokar | Bjerrum | CSN 73 1001 | ||
Frame structures and reinforced bearing walls | Structural | 1/150 | 1/250 | 1/200 | 1/150 | |
Cracks in walls | 1/300 | 1/500 | 1/500 | 1/500 | 1/500 | |
Type of structure | Type of damage | Ultimate relative deflection Δ / l | |||
