Hollow box girder
NettetThe standard precast girders shapes are: • Rectangular with depth exceeding the width • I-shaped with bottom flange wider than top flange • T-shaped • Hollow or box girder. Holes can be rectangular or round. NettetThe formula mostly used for all closed geometry made of slender members (like any box girder cross-section) is 4A^2/sum of (length/thickness) of all sides forming the closed …
