What is my seismic design category?
What is my seismic design category?
What is a Seismic Design Category. If A Seismic Design Category is a classification assigned to a structure based on it’s occupancy category, and the severity of the design earthquake ground motion. Seismic Design Category E – Corresponds to buildings of Occupancy Groups I,II and III in areas NEAR MAJOR ACTIVE FAULTS.
What is CS in seismic design?
Cs = seismic response coefficient determined in Section. 12.8.1.1 and 19.3.1 (dimensionless)
What is Risk Category II?
Most buildings and structures are considered to be Risk Category II. The IBC code defines essential facilities as “buildings and other structures that are intended to remain operational in the event of extreme environmental loading from flood, wind, snow or earthquakes”.
What is ASCE building code?
An integral part of building codes in the United States, Minimum Design Loads and Associated Criteria for Buildings and Other Structures (ASCE/SEI 7-16) describes the means for determining dead, live, soil, flood, tsunami, snow, rain, atmospheric ice, earthquake, and wind loads, and their combinations for general …
What are the four types of seismic zones?
Based on the past seismic history, Bureau of Indian Standards grouped the country into four seismic zones namely Zone-II, Zone-III, Zone-IV and Zone-V. Of all these four zones, Zone-V is the most seismic active region whereas Zone-II is the least.
What are seismic parameters?
Seismic moment, corner frequency and seismic energy are inverted from the spectra that are corrected for the instrumental, distance and attenuation effects of each waveform and then averaged. Seismic source parameters are not measured, they are estimated. There is a difference between a measurement and estimation.
What is seismic factor?
First, seismic/geophysical factors describe the magnitude and location of the earthquake, as well as the distribution of ground motion. Second, building factors describe the structural integrity of buildings in which people are located during earthquakes.
What is a Category 2 structure?
ASCE 7-05 – Minimum Design Loads for Buildings and Other Structures defines Category II as, “[a]ll buildings and other structures except those listed in Occupancy Categories I, III and IV.” Essentially, Category II is a catchall for any structures that don’t fall into the other categories.
What is Group 2 occupancy?
A facility that accommodates more than 5 persons “who are not capable of self-preservation” is classified as a Group I-2 occupancy, while a facility that accommodates 5 or less occupants “who are not capable of self-preservation” is a Group R-3 occupancy.
Is ASCE 7 a code or standard?
Developed by the American Society of Civil Engineers, ASCE 7 is an engineering code that provides a set of minimum requirements for the structural resistance of a building.
What does ASCE stand for?
The American Society of Civil Engineers
The American Society of Civil Engineers represents more than 150,000 members of the civil engineering profession in 177 countries. Founded in 1852, ASCE is the nation’s oldest engineering society.
What is called seismic risk zone?
A seismic hazard zone describes an area with a particular level of hazard due to earthquakes. Typically, a high seismic hazard zone is nearest a seismic zone where there are more earthquakes, and a lower seismic hazard zone is farther away from a seismic zone.
What is a seismic design category B?
Seismic Design Category B – Corresponds to buildings of Occupancy Groups I,II and III where expected ground shaking will be moderate. Seismic Design Category D -Corresponds to buildings and structures in areas expected to experience severe and destructive ground shaking But NOT located close to a major fault.
What is seismic design category C?
Seismic Design Category C – Corresponds to buildings of Occupancy Groups IV ( Hospitals, Police Stations Emergency control centers etc) I where expected ground shaking will be MODERATE AND buildings of occupancy categories I, II, and III where MORE SEVERE ground shaking will occur.
What is seismic classification?
Seismic Facies Classification. Seismic facies classification refers to the interpretation of facies type from the seismic reflector information. The key elements used to determine seismic facies and depositional setting are bedform internal and external configuration/geometry, lateral continuity, amplitude, frequency, and interval velocity.
What is a seismic class?
Seismic Design Category A – Corresponds to buildings in areas where expected ground shaking will be minor. Seismic Design Category B – Corresponds to buildings of Occupancy Groups I,II and III where expected ground shaking will be moderate.
