PATENTED SEISMIC EVALUATIONS
Patented Methodology
Seismic performance assessments directly based on sensing results.
Extract seismic engineering demand parameters such as accelerations, shear forces and drift based solely on sensing data
Does not require detailed structural drawings, known material properties, or the creation of finite-element models, removing conservative engineering estimates from analysis process
Based on the building properties in its current condition, including changes in material properties, connections and building response due to aging. Can be repeated rapidly post-earthquake to determine actual performance to aftershocks
Validated on over 80 earthquakes on the world's largest full scale 10-story shake table test and 5-story shake table test at the advanced UCSD facility in California, and at the UB 2-story building shake table
Sensing-based Seismic
Analysis.
• Based on real measured structural data that
includes the impact of any weakened structural
elements
• Generation of ground motions scaled according
to the seismicity of the building
• Modification of baseline properties based on
Sensequake's patented database from over hundreds of permanently instrumented structures in the past century that have suffered real earthquake motions
• Seismic time history analysis without creating a finite element model
• Engineering demand parameters can be used to
confirm or calibrate external finite-element
analysis to optimize designs and reduce costs
Seismic Performance Evaluation.
• Compare the generated seismic demands with
international codes and standards to obtain
seismic performance
• Global seismic evaluation of structural and non-
structural components based on HAZUS and
ASCE 41-17
• Component-level seismic evaluation using
FEMA-P58 standards
• Seismic performance evaluations without the
need for detailed structural drawings,
destructive tests or finite-element models
Global and component level damage prediction.
What Clients Say
"Ambient noise study proved to be a very efficient tool for the seismic response evaluation of the Centre Block, a primary heritage building of the Canadian Parliamentary Precinct in Ottawa. It highlighted, at an early stage, several aspects of the building response to seismic loads, aspects which will require special consideration during the design phase. At the same time, the ambient noise study was used for the calibration of the seismic analysis computer model developed by the structural consultants. Sensequake provided timely professional services for the test planning, data collecting and post-processing, working diligently on a very complex structural framing and many site constraints."
