Anchorage to concrete

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Has anyone on the list looked at the following sections in the 2007 CBC (2006 IBC)?

CBC 1911.1

ASCE 7-05 section

ACI appendix D


This would be the case when seismic loads are included in the design.


Based on this criteria for determining the allowable load on a 5/8” dia anchor bolt placed with in 1.75” of the edge (load parallel to the edge) is around 350# (service load) and 490# strength.


Are others on this list getting these values? The ACI appendix D equations are quite cumbersome.


I have not even considered the case where the load is acting on the bolt towards an edge.


This condition is common in wood frame design when bolting a mud sill to an 8” or 6” stem wall.
