* Applicable only for buildings

The 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 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

       roofs

   •   Specialized analysis for specific structural

       components such as joints to understand the true

       behaviour of the structure

After an in-depth baseline test, complete or simplified tests are done every few months, after a natural disaster, after retrofitting or during standard visual inspections. These are compared to the initial conditions to view any unseen changes in the structure's integrity and detect damage

• Complete: Full service tests examining the

                   frequency, mode shapes and                           modal curvature

• Simplified: Quick tests monitoring solely

                   structural frequency at a

                   reduced, competitive price

Permanent structural health monitoring solutions that can detect damage and assess integrity over time by monitoring the following:

• Simplified threshold alarms

• Structural frequency monitoring

 

• Deriving mode shapes

• Modal curvature comparisons

• Structural drift computation

• Feeding data into external or pre-existing

  systems

• Custom sensing parameters

* Applicable for all structures

 

Our vibration test can be used to monitoring any excessive vibrations with our Larzé sensors. These can be ran for long periods of time without direct access to electrical outlets and can be equally placed outdoors for no matter the use-case. This application can take the form of:

   - Vibration monitoring of sensitive equipment

   - Monitoring of ground-borne vibrations

   - Determining the transfer mobility

   - Measuring the building coupling loss

   - Conducting impact tests near construction zones

* Applicable for all structures

We can determine many parameters based on ambient vibration tests and our approach:

   •   Finding the resonance frequency of the subsurface soil

   •   Determining the fundamental site period

   •   Estimating the mean shear wave velocity of the

       uppermost 30 m

   •   Depth of bedrock

   •   The site classification and ground profile name

 

   •   By using the H/V technique: microzonation maps
