A MATHEMATICAL PROGRAMMING ALGORITHM FOR LIMIT ANALYSIS

It is well known from plasticity theory that there are two fundamental theore-ms, static and kinematic theorem, which can be used to determine lower and upper bounds of the collapse multipliers of proportionally loaded structures. According to these theorems the lower and upper bounds can be got by the maximization and minimization procedures, respectively. Both of the procedures can be formulated in mathematical programming forms, and related algorithm are constructed on these forms.In this paper attention...
