A Chicken Coop That Survives a Typhoon
Twenty tropical cyclones enter the Philippine Area of Responsibility in an average year and eight or nine of them cross the country, and the enforceable Philippine standard for broiler housing names two structural loads, neither of which is wind. The number that does exist sits in the structural code, one basic wind speed per province, and at four of the ten PAGASA stations checked here the strongest wind already on record is above the speed that province is designed against. What is left for a bakuran is not a stronger building. It is a signal, a lead time, and a decision about where the birds go.
