NOTE The y values may be set by the National annex. * For countries not mentioned below, see relevant local conditions. The characteristic value of seismic action for ULS verification is fixed by Eurocode 8 (EN1998), based on a return period of 475 years, corresponding to a probability of 10 of being exceeded in 50 years. It is possible to modify the return period by means of an importance factor yi. The frequent value and the quasi-permanent value of floor loads on building are determined so...

Pile Axial Force Bending Moment Diagram

Once determined x e as, the moment resistance results MRd - A'sfyd h-d' Asas -2-d P1xbfcd 2-P2x d In the fourth field NRd3 NEd NRd4 the moment resistance can be determined, with a good approximation, by the relation of proportionality indicated in fig. 6.8, which shows the final end of the interaction diagram M-N. Figure 6.8. Terminal end of the interaction diagram M-N The moment resistance reaches a maximum for x x2 where the analytic function that expresses it has an edge point due to the...

Stress Strain Relation For Concrete

Where t0 is the creep coefficient related to Ec , the tangent modulus, which may be taken as 1,05 Ecm as from Table 3.1-EC2 . Annex B of the Eurocode gives detailed information on the development of creep with time. Where great accuracy is not required, the value found from Figure 3.1 may be considered as the creep coefficient, provided that the concrete is not subjected to a compressive stress greater than 0,45fck tc at an age to. The values given in Figure 3.1 are valid for ambient...
