Reliability of diaphragm wall in serviceability limit states

The paper describes a procedure using serviceability limit state equations to calculate the reliability index for a laterally loaded diaphragm wall. The reliability indices related to the serviceability limit state have been obtained by creating two response surfaces: one based on the maximum lateral displacements of wall head and the other one using the maximum values of bending moments widening cracks in the wall concrete. The global reliability index has been obtained by using the appropriate system reliability formulae proposed by structural reliability theory.
