Module 1 Flashcards
1
Q
combination of actions definition
A
set of design values to confiirm that the limit states are not exceeded by combinations of the different actions
2
Q
limit state
A
state beyond which the structure does not meet the design criteria
3
Q
SLS
A
state beyond which the structure does not meet the servicibility criteria
4
Q
Uls
A
state associate with collapse or other structural failure
5
Q
structural robustness
A
ability for a strucutre to withstand explosions and shit without being damaged disproptional to the orignal case
6
Q
7 steps to deisgn procedure
A
define critical loads define load combinations (ULS SLS) define limit states (deflection etc) find the critical elements find the worst load for crit sections make an envelope of internal actions design memebers
7
Q
different load cases for a bridge
A
gravity earthwuake wind long term (shrinkage etc) traffic gravity traffic translational settlement
8
Q
influence lines definition
A
one dimensional function reperesenting the load at a point in the structure as a force moves along the axis
