Chapter 1 Flashcards
All major construction that is required to be safe against earthquakes needs input from the _____, the _____, and the ______.
Geologist, Seismologist, and Engineer
A type of fault wherein the crust is being pulled apart in which the overlying blocks moves down with respect to the lower block.
Normal Fault
A natural phenomenon that causes sudden and violent shaking of the ground which creates destructive tremors that causes building to collapse and faults to form.
Earthquake
What are the main causes of an earthquake?
Movement w/i the earth’s crust (tectonic plates) and Volcanic Eruption
This investigates the dynamic earthquake loading by replacing the dynamic effect with a force that is applied statically to a structure or a structural component at the center of mass.
Pseudostatic Analysis
One of the general approaches used to specify the earthquake motion that begins with the geological-seismological evaluation of earthquake sources and is carried up to a specification of the time histories that will be appropriate for the engineering site.
Site-specific approach
It is a ratio between the acceleration for an appropriate spectral content and the response in a structure with the ground.
Seismic Coefficients
It tests a structure by applying a cyclical load approximating that of an earthquake as it would be felt at an engineering site.
Dynamic Analysis
A type of fault where the crust is being compressed, in which the hanging-wall block moves up and over the footwall block.
Reverse-fault
True or False.
Where a pseudostatic analysis is to be done, usually no specific geologic or seismologic investigation is needed.
True
