Abstract
The paper presents a computer procedure to evaluate the collapse load and the
collapse mechanism of three-dimensional structures made of rigid blocks with
no-tension and frictional interfaces based on mathematical programming.
Using the theorems of non-standard limit analysis, the algorithm searches the
minimum statically admissible load factor, which ensures a possible
mechanism. The presence of friction makes the problem non-linear and
difficult to solve. The possibility to detect the optimal solution using a quasifeasible
initial estimate of the unknowns is shown. This is obtained as the
solution of a linear programming problem corresponding to a system of blocks
with dilatancy
