How do I know my seismic design category?
If you are unsure of what Seismic Design Category (SDC) your project may fall under it can typically be found in the structural notes section of your construction drawings, or they may also be listed in the project specification.
What is SS and S1 seismic values?
Ss: Spectral acceleration parameter at short periods corresponding to the mapped maximum considered earthquake. S1: Spectral acceleration parameter at a period of 1 sec corresponding to the mapped maximum considered earthquake.
What is a site class?
The Site Class Definition quantifies the soil’s propensity to amplify, or in some cases decrease, surface ground motion propagating from underlying rock. The Site Class Definition is also used by designers to determine the Seismic Performance Zone for a structure (3.10. 6).
What is seismic class B?
For Seismic Design Category (SDC) B, which designates a low seismic hazard region, structural engineers still need to complete a full seismic design process to meet the building code requirements.
What are seismic zones Class 8?
Seismic zones: Seismic zones or fault zones are the boundaries of lithospheric plates at which the earthquakes generally occur. Seismograph: An instrument used in the measurement of seismic waves is called seismograph.
What is seismic zone III?
Zone 3. This zone is classified as a Moderate Damage Risk Zone which is liable to MSK VII. The IS code assigns a zone factor of 0.16 for Zone 3. Several megacities like Chennai, Mumbai, Kolkata and Bhubaneshwar lie in this zone.
What is soil Class D?
Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet.
What is Plate Class 8?
The crust of earth is made of many huge pieces of flat rocks. Each piece of the earth’s crust is called a plate.
What is discharging Class 8?
Discharging: The process of release of electric charges from a charged object to an uncharged object in contact with it, until the charges on both the objects become equal is called discharging.
What do you mean by seismic zone class 8?
What is sparking class 8?
Causes of sparking: (i) On electric pole wires become loose. (ii) Blowing of wind and shaking the wires. (iii) Looseness of plug in its socket.
