Building Façade(s) Seismic/Differential movement check:
The purpose of this procedure is to check that the test specimen (façade build-up) can accommodate movements that may occur as a result of building movements arising from differential settlement, seismic sway or exceptional wind sway.
Seismic- Structural Movement (AAMA 501.4-00-CWCT Section 17)
The differential movement created both sway & vertical is applied gradually to the specimen supports and the specimen observed for damage. the movement is created by a fixed hydraulic ram(s) & a control station, the differential movement /measurement in (mm) is set by a calibrated device before the test commences -a basic schematic of the functionality of the hydraulic ram and pump is below.
Vertical stacking joint movement
One cycle, from nominal to max. To min. to nominal) The vertical movement is measured across a structural bay in a true curve.
Lateral sway
Test at design displacement (AAMA 501.4-00) the inter storey drift [sway]
