PATENTED SEISMIC EVALUATIONS

We offer rapid and detailed seismic screening based on testing.

Traditional methods of seismic evaluations require highly detailed structural models of a building to be created. Our patented approach to seismic analysis allows for rapid seismic evaluations based solely on on-site testing. Testing can be conducted on buildings where structural plans are not readily available and can be done rapidly -- ideal for large portfolios. These tests can be done on global or component-based levels in order to determine the likelihood of damage, the estimated damage costs and the estimated repair times for any given structure.

Sensequake's seismic analysis services can be used on their own to quickly quantify and assess seismic risk or to optimize seismic rehabilitation designs. The detailed performance-based evaluation conducted by sensing is the ideal approach for complex structures, historic buildings with few structural drawings, large building portfolios, or small structures without needing detailed finite-element models.

Seismic
Analysis

Calculation of global seismic demands based on time-history analysis without finite element models including:

   •   Generating ground-motion time histories

   •   Response histories such as drift ratios, displacements,

       accelerations, forces, base shear and overturning

       moments at any location and direction on the building

   •   Calculations of maximum global seismic demands

       along with the height of the building for the desired

       number of ground motions

   •   Modifying ambient vibration modal properties to

       converting them to the higher shaking level modal

       properties based on Sensequake proprietary

       databases

   •   Displacement and acceleration response spectra at

       any location in the building

 

   •   Determining the static force to design ​non-structural

       components

   •   Two-phase finite element model optimization. Initial

       phase based on modal properties and a second phase

       by comparing the seismic demands generated by our

       approach and those of the model in order to calibrate

       it to the building's actual properties within a desired

       accuracy

Global Level Seismic Damage Prediction

Compare global seismic demands with the damage thresholds of various standards and codes: 

  •   Global seismic evaluation of structural components

      based on HAZUS and ASCE 41-13 criteria

 •   Seismic evaluation of drift-sensitive non-structural

     components such as infill walls

 •   Seismic evaluation of acceleration-sensitive non-

     structural components such as piping systems,

     suspension ceilings and general equipment

Large scale portfolio triage and management for prioritizing and optimizing maintenance budgets and optimizing decision making

Component Level Seismic Damage Prediction

An in-depth, component-based analysis where the simulated seismic demands are compared to the FEMA P58 standards allowing us to quantify: 

   •   Component-level damage severity

   •   Repair time estimations

   •   Expected repair costs

Rate building performance based on USRC and REDi guidelines and assess their expected level of seismic performance
