Snow load calculation (ASCE 7), explained
ASCE 7 turns ground snow into a roof snow load with a handful of factors. Here is the flat-roof and sloped-roof formula, what each factor means, and a worked example.

Load combination worked example
One column, every gravity combination, worked end to end in both ASCE 7 and Eurocode. See exactly how service loads become a governing factored reaction.

Eurocode vs ASCE 7 load combinations
ASCE 7 and Eurocode reach similar safety by different bookkeeping. Here is a side-by-side of the gravity combinations, the factors, and a worked comparison.

ASCE 7 load combinations explained
ASCE 7 gives the factored load combinations that size members. Here are the gravity LRFD and ASD combinations, what the factors mean, and a worked example.

What is the governing load combination?
The governing load combination is the one that produces the largest design effect on a member. Here is how to find it, why it varies, and a worked example.

Load takedown, floor by floor: a worked example
A column reaction is just every floor above it, added up in the right order. Here is a full three-storey gravity takedown worked by hand, from slab pressures to a factored foundation load.

ASCE 7 live load reduction, explained simply
A column carrying ten floors is not realistically loaded to the full design live load on every one at once. ASCE 7 lets you take credit for that. Here is the formula, the K_LL factors, and a worked reduction.
