Load distribution influence on the mechanical state of reinforcement concrete structures of a port storage facility

Abstract

The stress/strain state of reinforcement concrete walls and foundation plate of a storage facility in the seaport of Klaipeda (Lithuania, the EU) is investigated, considering the distribution of loads from stored bulk materials. At the first, a simple test problem has been calculated: reinforcement slab 21´35 m in plane on 24 columns, which are located by a regular step. During creating the combinations of all 15 possible loadings of each „cell“, increased internal forces and reinforcement results to +20 % have been obtained. Next, a storage facility of bulk materials with dimensions 36´120 m in plane has been considered, when expected 16 loadings, 1/4 for each of four storage sectors, has been used in the FEM model. The results of the comparison with the ordinary calculation, in which each of sectors could be fully filled or be empty, have presented. The investigation results can be used for developing of industrial recommendations for the designing of storage facilities.
