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....
An interior roof equipment screen wall can be designed for the forces in section 29.4.1, Rooftop Structures and Equipment for Buildings. This provision takes into account the elevation of the screen wall, which is the concern if using a freestanding wall load. This also answers the second part...
What is the proper wind load for a freestanding equipment screenwall in the field of a roof (ie outside edge zones 2 or 3)? Parapet pressure does not seem pertinent as the wall is a substantial distance from the edge of the structure. The freestanding wall load methodology seems somewhat...
Pete The intent of Section 12.13.9.3.4 is to assure that if lateral spreading occurs, and imposes permanent lateral deformation of the pile along its length, that the pile will still be able to sustain the gravity loads imposed on it and not cause collapse. The degree and rigor of analysis...
Good Day, This is my first posting, so I am grateful for any feedback/input. We have some discussions in our office related to Provision 12.13.9.3.4 in ASCE 7-16, in particular: Is the intention of this provision such that the engineer is to perform a p-delta analysis with secondary effects on...
