Temporary Shoring

[teckert]

Does anyone know if why temporary shoring is designed with LRFD theses days- it seems so much more confusing for a temporary structures. In addition, its not as if ASD is unsafe?

Thanks,

teckert - who is insisting that LRFD must be used? Seems like it would be up to the engineer doing the designing. Most of the construction engineers I've worked with use ASD for shoring.

ASD is more conservative, so use it if you wish.

BA- with higher live loads, LRFD results in a more conservative design due to the higher SF on live loads than on DL?

Use ASD, not because it is conservative but because you need to deal with the actual forces when designing shoring. For example is you shore a concrete structure and you need to jack the shoring to relieve stresses, you need to use ASD to determine the stresses.
