New steel design

Project
Plan drawing
The column grid, columns, outline and openings are read from the architect's plan; stories, heights, use, loads, wind, earthquake and soil from this form.
Shed

Rigid portal frames, one span or several side by side on interior columns, with purlins, girts, rod bracing in the end bays and pad footings. Roof slopes up to 10°; no cranes or mezzanines yet.

From the drawing: the spans and the frame spacing (frames on the grid lines across the longer side; a line of columns at every frame is an interior column line).

Column-free areas

Halls or showrooms where no column may stand, in meters from the plan's lower-left corner. Columns inside are removed and transfer girders designed.

Loads
WindWind and snow

Pressures vary with height (qz = 0.613 Kz Kzt Kd V² I); windward and leeward walls; 1.6 W at strength level, 0.7 W for drift. The table is in the report.

ASCE 7-22: V at strength level for Risk Category II (1.0 W); Kz from Table 26.11-1; drift under the 10-year wind. Snow pf = 0.7 pg with the low-slope minimum, as 1.0 S. Confirm the site's values with the ASCE Hazard Tool.

Earthquake
Foundations

From the soil report. Spread footings, combined and strip footings, mats and pile groups are considered in that order.
