CANDE--A MODERN APPROACH FOR THE STRUCTURAL DESIGN AND ANALYSIS OF BURIED CULVERTS
A unified computer methodology is presented for the structural design, analysis, and evaluation of buried culverts made of corrugated steel, aluminum, reinforced concrete, and a class of plastic pipe. Through proper representation of soil-structure interaction, the engineer can test and evaluate either old or new culvert design concepts. The engineer may select any of three solution levels in the computer program, depending on the complexity of the problem and vigor of solution derived. Level 1 is a closed-form elasticity solution (Burns), whereas levels 2 and 3 are based on finite element methods. Each solution characterizes the culvert-soil system by plain strain geometry and loading. Analytical modeling features incremental construction and non-linear constitutive models for characterizing culvert and soil behavior. Culvert material models account for ductile yielding and brittle cracking. CANDE designs are compared with traditional design solutions for both corrugated metal and reinforced concrete pipe. Field experimental data compared to CANDE predictions demonstrate good condition. /Author/
