TOPIC 8 Flashcards
It is the phenomenon where
saturated soils lose strength and behave like a liquid during strong ground shaking.
- LIQUEFACTION
This involves assessing the
ikelihood of an earthquake occurring, its potential size, and the resulting ground shaking over a given period.
- SEISMIC HAZARD ASSESSMENT
During earthquake shaking, the
columns undergo relative movements between their ends.
This movement is shown as quantity
—between the roof and their ground
- U
Diaphragm acts as ______ Transmitting loads effectively during an earthquake.
- HORIZONTAL BEAM
Diaphragms are structural elements
(typically floors and roofs) that
to vertical load-
resisting components like walls and columns.
- DISTRIBUTE SEISMIC FORCES
This method considers all possible
earthquake scenarios and their likelihood of occurrence.
- PROBALISTIC SEISMIC HAZARD ANALYSIS
This is a useful building technology
that helps transfer earthquake forces,
- SHEAR WALL
For a material to resist stress and
vibration, it must have
- HIGH DUCTILITY
What is the seismic zone factor of
Puerto Prinsesa?
- 0.20
To consider the effects of
earthquake forces at some angle other than those two principal directions,
must be considered
- ORTHOGONAL EFFECTS
