Title
Earthquake-Resistant Design Advisory 1991
Law
Dpwh Memorandum
Decision Date
Sep 5, 1994
The DPWH Memorandum provides essential guidelines for earthquake-resistant design in buildings, emphasizing compliance with the National Building Code and addressing specific challenges in areas prone to liquefaction and landslides.
A

Reference Material for Earthquake-Resistant Design

  • The Association of Structural Engineers of the Philippines (ASEP) has published the "ASEP Guide to Earthquake-Resistant Design, 1991."
  • This guide is recommended as a reference for engineering professionals in their design work to ensure earthquake resistance.

Advisory on Areas Prone to Liquefaction

  • Special advisory is issued regarding locations susceptible to soil liquefaction during an earthquake.
  • Design engineers are specifically advised to incorporate considerations for liquefaction into their structural designs to mitigate potential damage.

Advisory on High Elevation and Slope Areas

  • Additional advisory is given for buildings on high elevations and slopes where landslides may occur.
  • Engineers must consider the phenomenon known as "ridge amplification" which may exacerbate seismic effects in these areas.
  • These considerations should be integrated into the structural design to enhance safety and resilience.

Purpose and Enforcement

  • The advisory aims to guide engineering professionals, particularly Structural Engineers, in earthquake-resistant design.
  • Issued by the Department of Public Works and Highways (DPWH) as a directive for information and compliance.
  • Adoption Date: September 5, 1991
  • Signed by Secretary Jose P. De Jesus as an official advisory to uphold engineering standards and mitigate earthquake damage risks.
