Wind Research

This is a running list of wind engineering research in the Philippines that could be carried out by interested students and researchers.

1. General

• Philippine National Standard (Code) development.  Review of historical development.  Review of current provisions.  Comparisons with current international codes.
• Wind Tunnel Testing procedure*.  Design/selection of WT type for Philippine conditions.
• CFD for structural wind design purposes*.  Reduction of errors.  Correlation with full scale measurements.
• Scenario typhoon...  similar to MMEIRS output.
• Redundancy design against progressive collapse of residential building under typhoons.
• Characterization of wind-borne missile trajectories and effects on building envelopes.
• Delphi method to analyze non-engineer's damage photos.
• Research topics wiki. (e.g. this post)

2. Improvement of Wind Hazard Identification

• Online Real-Time Updated Wind Hazard Map
• Monte-carlo simulation of typhoon tracks and intensity, and development of 500-, 700-, and 2500-year return period wind speed maps, and wind directionality factors.
• Typhoon wind (vertical) profile, and comparison with NSCP 2001 wind profile and effects on existing structures.
• Engineering Survey of PAGASA meteorological stations to arrive at correction factors.
• Optimum location of new meteorological stations... using Kriging Method?
• Terrain exposure categorization and topographic effects calculator using Google and other Maps

3. Dynamic response - buildings

• Relationship of damping and non-linear response of... Buildings?
• Target performance levels for certain return periods.
• Further processing of vibration data of 100 buildings in Metro Manila to determine damping values... using SSI, and/or RD method.
• Full-scale natural frequency and damping measurement correlated with wind speeds at time of measurement.
• For what types does wind load govern over earthquake loads in the primary LFRS design?

4. Dynamic response – steel lattice structures

• Relationship and damping and non-linear response of... Non-building steel structures?
• For what types does wind load govern over earthquakes in the primary LFRS design?
• Measurement of natural frequencies and damping of trussed structures (towers and billboards) in the Philippines...
• Addressing issues in scaling effects on wind tunnel testing of lattice structures for estimating dynamic wind effects... http://www.google.co.uk/search?hl=en&q=wind+tunnel+testing+of+lattice+towers&meta=&rlz=
• Quantification of effects of fatigue due to wind loads...  Additional load factor to account for fatigue?

5. Dynamic response - general

• Code- or design-dependent factor... GENERIC natural frequency estimator (formula)

6. Low-cost housing

• Minimum nail and tie-down design for roofs, and general wind-resistant design of low-cost housing... (e.g. for Haiti)
• Full-scale measurements of various low-income construction types... in Catanduanes (i.e. very high wind speed region)!?
