Good Afternoon The Equation, in ASCE 113 2nd Edition, for determining values of Short Circuit Forces in Aluminum Rigid Bus in a Substation, is presented in Section 3.1.8.1, Eq. 3-38. To account for partial decay of the DC component of the fault force a Decrement Factor, defined in Eq. 3-42, is...
I'll let others on the 113 committee weigh in, but the Example A.1 goes over a bus support structure that is a frame in one direction and a cantilever in the other. We don't have seismic loads in my part of Texas so I will defer to the people on shaky ground. :) Equation 3-11 and 3-12 are for...
Hello all, while designing structures per ASCE 113 Second Edition we ran into a double equation for a seismic force. There are two different equations to calculate a seismic force. One is stated to be used for structures (Equation 3-11), while the other is stated to be used for "rigid bus...
Guidelines for the Physical Security of Water and Wastewater/Stormwater Utilities, ASCE/EWRI 78-24, provides guidelines on the evaluation and enhancement of physical security of facilities used in potable water sources, treatment, and distribution systems, as well as for wastewater and...
ASCE/SEI 74-23, is intended for use in the design of new buildings and other structures constructed of pultruded fiber–reinforced polymer (FRP) composite structural shapes, connections, and prefabricated building products. It addresses pultruded FRP structural shapes that have symmetric and...
ANSI/ASCE/EWRI 33-23, serves as a comprehensive framework designed to assist riparian governments in effectively managing shared water resources. This agreement offers practical guidance for national and state governments, as well as other stakeholders involved in establishing water quality...
Standard 39-23, provides a general overview of the science and technology of hail suppression combined with specific strategies and procedures required to design, conduct, and evaluate hail suppression operations. Such operational activities as airborne, ground-based, and rocket and artillery...
The 2015 International Building Code (IBC) in chapter 1807.2.1 states that when a keyway is extended below the wall base to engage passive pressure and enhance sliding stability, the lateral soil pressures on both sides of the keyway must be considered in the sliding analysis. However, this...
