ABSTRACT
The purpose of this thesis is to investigate the failure
strengthof several suspended ceiling systems often used in
Taiwan. The first part of this thesis is to
analyze the mode shapes ofceiling systems and perform time
history analysis with SAP2000.Therefore, the dynamic behavior
of different ceiling systems underlarge vibration can be
observed and compared to experimental results. The second
part is to exam damage testing of several full scaleceiling
mode including non-bracing、 bracing and suspended
strutssystems on shaking table, with or without some light
fixture. Observations from this study are:
1. When Attacked by both vertical and horizontal
earthquake, the strength of ceiling systems is less than
those attacked only by horizontal earthquake.
2. The boundary condition is very important for strength of
ceiling systems. Lateral stiffness of the ceiling grids
will influence strength in the perpendicular direction.
3. Runners and boards near supporting edge fail more often than
others4. Bracing system does not show better strength than
non-bracing system in performed tests.
5. Although not having higher strength when loaded by only
horizontal earthquake, suspended strut system has better
strength when loaded by combined vertical and horizontal
earthquake.
