TOPIC 2 Flashcards
Occupancy category of structures with the highest priority of function and
seismic importance factor.
ESSENTIAL FACILITIES
It is a horseshoe-shaped zone that stretches around the edges of the Pacific
Ocean, covering areas such as the west coast of North and South America, Japan, Southeast Asia, and
the islands of the Pacific Ocean.
THE RING OF FIRE
What zone that requires stricter and special consideration in building infrastructure?
ZONE 4
It is the accounts for the effect of site soil conditions during ground motion.
SOIL PROFILE TYPE
These are the fractures that occur between two landforms that allow them to move
relative to each other.
FAULT LINES
-Measures the resistance of the soil to penetration, providing an
indication of its density and stiffness.
STANDARD PENETRATION TEST
Defines the maximum moment magnitude that a seismic source can be
categorized.
SEISMIC SOURCE TYPE
What type of soil requiring site-specific evaluation.
SF
-The biggest fault line in the Philippines known as the Valley fault system (VFS), is a
dominantly right-lateral strike-slip fault system in Luzon, Philippines.
MARIKINA VFS
-A measure of how quickly seismic waves travel through the soil
SHEAR WAVE VELOCITY
