STRUCTURAL BEHAVIOR OF A SKEWED, PRESTRESSED CONCRETE, RAILROAD TROUGH STRUCTURE - FINITE ELEMENT ANALYSIS OF AN ALTERNATIVE DESIGN (PART 2). FINAL REPORT

Prestressed concrete, trough-shaped railroad structures built in California have manifested a propensity for extensive, early age cracking. Field and analytical studies of the Land Park Underpass have suggested confinement of exothermic heat of hydration in the massive elements as a primary cause. One suggested alternative design solution would employ open, cellular sections in lieu of the massive, solid sections previously used. A finite element analysis of such a structure, the South L.A. Underpass, has been performed as part of the design process. The report furnishes a step-by-step description of the procedures used as a pattern for future analyses with the program FINPLA.
