National Structural Code of the Philippines 2010

Chapter 1, Section 105 105.2 Earthquake-Recording and Instrumentation 105.2.1 General Unless waived by the Building Official, every building in Seismic Zone 4 over 50 m in height shall be provided with not less than three approved recording accelerographs. The accelerographs shall be interconnected for common start and common timing.

Benefits of Installing Accelerographs

BETTER SEISMIC DESIGN

  • 1. Prove the dynamic model used in the building design process
  • 2. Validate or improve seismic design codes

RAPID ASSESSMENT AND DAMAGE MITIGATION

  • 3. Monitor structural response during an earthquake
  • 4. Provide information used in post-earthquake actions
  • 5. Interact with automatic shutdown controls to minimize damage
  • 6. Provide data useful to the retrofit process

BUSINESS CONTINUITY

  • 7. Reduce the monitored structure’s post-earthquake non-operational downtime

THE BIG PICTURE

FOR POLICY MAKERS FOR OWNERS AND OPERATORS FOR FACILITY MANAGERS FOR OCCUPANTS AND RESIDENTS Improve safety mandates for the public and showcase the city’s growth Save money by reducing downtime and continue business as usual Better manage decisions on evacuation and reoccupation Increase confidence in safety and avoid panic during state of emergency
