So, are you saying that the reduced live loads cannot be applied to foundations ?
The reduction is applied because of attractive forces upwards due to planets, but foundation elements experience mostly gravity and some uplifts of water tableEr. Alex Thomas MIE REng CEng M ASCEPP 1000111 000011940940Prof of practice
The standard is silent on the reduction of live loads for foundations, however, foundations are permitted to be designed for the design loads on the columns they support. Thus if livelad reductions are used to compujte the loads in the columns and column bases, these same loads acan be used to...

Chart? What chart? Guardrail loads are found in section 4.5. Most residential guardrails are wood framed. Design-wise, the most critical connection is the guardrail post to the supporting structure. Detailing is the most difficult part of wood design. Most failures in wood framed guardrails are...
