DIAGRAMI ZA STATIČNO RAČUNANJE OKROGLIH REZERVOARJEV - RECENZIJE

Diagrams for cylindrical tank analysis
Sheet I contains diagrams yielding -all data on internal forces (axial forces, bending moments and shear stresses) for a circular wall fixed on the bottom and loaded to the top with liquid. Sheet II contains diagrams for internal stress values in the same wall f-or the case of a bottom joint -rotation by which the shell stiffness is determined. All internal stresses are plotted against the ratio
H2 . (Height of tank)2
--- i. e.----------------------------•
Rd Radius x thickness of wall
In the case of shallow tanks all diagrams ram-i-ficate in two branches: the first is valid for tanks having at the top of the wall a free edge and the second for such having a side supported top edge.
To the diagrams a paper is added with the following contents:
Theoretical basis of cy-lindrioal tank analysis with mathematical differentiation.
Detailed -explication of diagrams.
Consideration on elastic fixity of the wall cm the bottom.
Consideration -on influence -of transverse strain.
Application o-f diagrams to rectangular tanks.
Formulae for the distributon of internal stresses in a fixed circular slab.
Three illustrative problems are attached.
The purpose of the diagrams and the paper is to permit a relatively quick and simple analysis of tanks. This method should give results which lie as near as possible to a probably rea-1 distribution of internal stresses.
