In ASCE 7, velocity pressure qz is proportional to the basic wind speed in what way?
Answer: Squared
qz = 0.00256 Kz Kzt Kd Ke V², so pressure scales with the square of wind speed.
For Risk Category II buildings, ASCE 7 basic wind speed maps correspond to approximately what mean recurrence interval?
Answer: 700 years
Risk Category II wind speeds are based on about a 700-year mean recurrence interval.
Before exposure and thermal factors are applied, ASCE 7 flat roof snow load equals what fraction of ground snow load?
Answer: 0.7
pf = 0.7 Ce Ct (Is) pg, so the base conversion factor is 0.7.
In ASCE 7 seismic design, how is the design spectral acceleration SDS related to the MCER spectral acceleration SMS?
Answer: SDS = 2/3 SMS
Design values are two-thirds of MCER values, reflecting an assumed margin against collapse.
According to the ASCE Code of Ethics, what must engineers hold paramount above all else?
Answer: The safety, health, and welfare of the public
ASCE's ethics code puts public safety, health, and welfare above all other obligations.
Which sustainability rating framework, co-founded by ASCE through the Institute for Sustainable Infrastructure, evaluates civil infrastructure projects?
Answer: Envision
Envision, from the Institute for Sustainable Infrastructure, rates sustainable infrastructure projects.
In value engineering, what is a project element's value defined as?
Answer: Function divided by life-cycle cost
Value engineering aims to deliver the required function at the lowest life-cycle cost.
