Structural Health Monitoring System (SHMS)

Key points

• Identify damage intensity and possible location(s)• Coordinate emergency response• Prevent unnecessary evacuations• Reduce costly downtime and minimize distress• Enhance public safety

SHMS is a cost-effective real-time monitoring solution, whichmay help to:

Solution

Our Structural Health Monitoring System (SHMS) provides the continuous monitoring of a building or infrastructure frequency, ambient noise, movement and behavior essentially giving the building a measurable pulse with SeismicDataSensors tuned to a building via engineers.

Allowing informed decision around seismic events or degradation over time. The continuous real-time monitoring of your building or infrastructure may allow you to identify and respond before an earthquake has a serious impact on your operation or finance.

Current issues

Building by building assessment is the norm. This can take weeks, months oreven years.

Earthquakes are a global fact of life. There are a myriad of fault lines around our world, any of which could pose a threat to life and cause significant financial and social upheaval.

Earthquakes are also well recognised as a workplace hazard. It is therefore vital that easy access is provided for rapid accurate information on your building status to improve decision making affecting life safety outcomes.

Recent events are a sharp reminder that complacency is not an option in the event of a major earthquake.

Global Seismic Data – Three pillared approach

• A greater effort to understand risk (in all dimensions) so that investment can be prioritised through better risk-informed decisions and building resilience into everyday processes.

• A broader whole of society approach to risk.

• A shift of focus from managing disaster to managing risk, including reducing the underlying drivers of risk (exposure and vulnerability).

Protecting lives – Future & real-time assessment

Everyone has a role in reducing and managing riskIt also delivers worldwide transformational change for engineers, buildings and infrastructure owners, insurers, people and communities.

Valuable dataBy knowing what is occurring within and to a building, or what has happened, the living and operating environment of a community is significantly enhanced. They have:

Better trust• The use of objective numbers as a decision-making aid• Clarity around the best courses of action following a seismic event• The certainty that everyone is “Singing off the same hymn sheet” in structures’ health

Removal of fear and uncertainty• Real time information leading to informed ‘next steps’• The elimination of guesswork• ‘What you measure, you can manage’

Better ways of protecting life and business• Improved emergency management planning and execution• Improved buildings and other infrastructure• Improved communication outcomes within and across shared stakeholder interests

List of buildings

Within minutes of a quake finishing, view list of your buildings and status based on peak ground acceleration. Building owners, engineers, facilities can get a quick overview of a building or portfolio.

Backend engineer view

Shows the event, number of sensors triggered, links to GNS or USGS event, the perceived shaking and MMI level based on data.

Backend engineer view

Shows event, sensors that triggered, acceleration on north/south, east/west and vertical in G force

Event data

The event data can be downloaded by engineers in a CSV file

Data breakdown by floor

Click on the floor number to remove floors viewed

Displacement• View displacement as either absolute, relative or inter-story drift • Acceleration can be simple, constant or linear, adjust frequency• Isolate floors

Response spectra• Response Spectra can be shown as overall, axis, sensor or trace• Damping can be adjusted as well as period resolution, maximum period and measure

Response spectraUsing the acceleration data, we can calculate the response spectra for the floor on the X, Y and Z axis (vertical)
