STRESS ANALYSIS OF CONCRETE SECTIONS UNDER SERVICE LOAD

The stress analysis of concrete sections under service load is complicated by the interaction of shrinkage, creep, elastic strains of concrete and steel, and steel relaxation. Further complications arise in the case of partially prestressed concrete structures, with cracked cross sections under service load and with mixed reinforcement consisting of a combination of prestressed and nonprestressed reinforcement with individual mechanical properties and different effective depths. Combinations of sustained and instantaneous loads also complicate the analysis, whereas compound bending is easily taken into account. An analysis is suggested covering these problems in cases of symmeterical bending. /Author/
