Development of wind damage bands for buildings

1. Damage band reveals that the wind damage responses of individual 1-3 story buildingsis most easily distinguished in the 43-60 m/s (sustained one-min mean) wind regimeand that above 73 m/s sustained one-minute wind speed, 1-3 story buildingsexperience near-total destruction of their superstructures, with the damage responseof the most wind-resistant and least wind-resistant building approaching each other.

Development of a Rapid Condition Assessment tool for Reinforced Concrete MomentResisting Frame Buildings in the Philippines: Structural Component

The RCAsT uses a basic structural score that is modified based on differences inattributes of the existing building and the base structure. These scores werederived using fragility curves for locally built structures.

Vulnerability curves are funcitons of the damage ratio and the ground motionintensityFragility curves provide the probability of exceednace of a particular damage state.

The RCAst structural component has two major parts that are used to assess thestructural condition of the buildings.The first part uses basic structural hazard score and score modifiers that werederived using fragility curves for low and mid-rise reinforced concrete frambuildings in the Philippines. Included in this part is a scre modifier fornear-source earthquakes which is not used in FEMA-154 but included in theprovisions of the NSCP 2010.

Initial basic scores were derived using this definition together with thefragility curves developed by the UPD-ICE. However since the fragility curvesused in the derivation were different from the ones used in HAZUS, theresulting scores were too small and the score modifiers were not meaningful.

Basic structural hazard score modifiers1. eleveation of the structure2. irregularities present in the structural configuration3. code used in the design of the structure4. soil profile type5. nearness to a fault line

Fragility curves developed by UPD-ICE for CHB is based on a compilation ofempirical observations of damage for corresponding ground motion intensities interms of Modified Mercalli Intensity (MMI) from past earthquakes in the Philippines.
