Question & AnswerQ&A (DPWH MEMORANDUM)
The main purpose is to provide guidance to engineering professionals, particularly Structural Engineers, on earthquake-resistant design of buildings and related structures to mitigate damages due to earthquakes.
The design must conform to the current National Building Code and its referral codes, particularly the National Structural Code of the Philippines, Volume I, Revised Edition 1991.
The Association of Structural Engineers of the Philippines (ASEP) published the ASEP Guide to Earthquake-Resistant Design in 1991.
Design engineers are advised to address the problem of liquefaction in their design to ensure the earthquake resistance of the structure.
A special advisory is given for areas on high elevations and slopes subjected to landslides and the probable occurrence of ridge amplification.
Ridge amplification refers to the increase in seismic shaking intensity at ridges or elevated terrain, which should be considered in the structural design to prevent damage during an earthquake.
The intended audience is engineering professionals, particularly Structural Engineers, involved in design and construction of private and public buildings and related structures.
The minimum requirement is conformance to the National Building Code and the National Structural Code of the Philippines, Volume I, Revised Edition 1991.
