In the Guide to the Snow load Provisions of ASCE 7-22 (O'Rourke, 2023), on page 29 there is a paragraph that alludes to Table 7.3-3 "Thermal Factor, Ct, for Heated Structures with Unventilated Roofs" needing to be replaced with Table G3-7 from the Guide. The reasoning in the Guide is that Table...
Here's a brief overview: Soil Compressibility 1. *Definition*: Soil compressibility refers to the reduction in soil volume due to applied loads, causing settlement and deformation. 2. *Factors Affecting Compressibility*: Moisture content, soil type, density, and stress history....
For Risk Category II, Importance Factor of 1.0 Nonstructural Component in a Seismic Category C site, ASCE 7 Chapter 13 (Table 13.1-1) requires positive attachment of the component but otherwise is excluded from the requirements of the chapter. If that nonstructural component is analyzed for...
I think I have answered this question for myself. When looking at ASCE 7-22 Figure 30.4-1 Note 4 they indicate +GCp values use qz and -GCp values use qh. I think +GCp are representing windward walls and -GCp are representing side and leeward walls. I was incorrectly considering both +GCp and ...
In ASCE 7-22 Ch 30 Pt 2 is the criteria for components and cladding for a tall building with h > 60 ft. The equations use q and qi, and in the case of the walls (zone 4 or 5) the values are dependent upon whether it is a windward, leeward or side walls. In the case of Components and Cladding we...
The vertical combinations requirements are intended for the case where one lateral force resisting system is used for an upper portion of a structure, and a second (or third) is used for the lower level(s). As an example, consider a three-story light wood (or CFS) frame structure mounted on top...
