Besides standing cylindrical fluid tanks for gaseous materials saddle supported cylindrical tanks are used for the transport of goods in general. The storage and the transport of dangerous goods represent an enormous risk potential for humans and environment. To minimize this risk the legislator makes numerous demands on the operation and the technical design of such tanks. In particular the knowledge of the carrying behaviour for all foreseen arising loads is important for the technical design. These are beside loads from operating pressure and vertical load also horizontal loads. Thus the \"Verordnung über die innerstaatliche und grenzüberschreitende Beförderung gefährlicher Güter auf der Straße und mit Eisenbahnen\", briefly GGVSE, with reference to \"Anlagen A and B des Europäischen vom 30.September 1957 über die internationale Beförderung gefährlicher Güter auf der Straße\", briefly ADR, demands the separate proof of stability for tanks under a horizontal transverse force amounting to the gravityload. Whereas for the vertical load case both static and dynamic investigations lead to the today valid practical design aids and calculation formulas published in the \"AD-Merkblätter\" and the \"British standard 5500\", such investigations and design aids are not present for the case of the horizontal transverse load. This dissertation helps to eliminate this deficit and thus to enable a final estimation of the carrying behaviour under consideration of the static and dynamic horizontal transverse load. The development of calculation formulas and design aids should help to estimate the carrying behaviour. Therefore the dissertation is arranged into two parts; a first part, which deals with the stress in the shell under the dynamic horizontal transverse load and a second part, which deals with static calculation and takes the results of the dynamic research into account. In the first part dynamic experiments on a saddle supported cylindrical tank are made. Therefore the tank is stored on two concrete saddles. The saddles are fixed with a sub-construction of doublesymmetrical steel girders. This construction is oscillated in transverse direction. The charge of the tank (charge: water), the distance to the head stiffeners to the saddles and the frequencies are varied. In each experiment the circumferential and logitudinal strains, the accelerations and the contact pressure distribution between the shell and the saddle are measured. The results of the test series serve as reference for a finite element modelling. In this finite element model (fem) the load distribution on the cylindrical wall due to the dynamic horizontal load is of substantial interest. The comparison of the stresses measured in the experiment with the computation results based on a timedepent load distribution, serves as acknowledgement of the chosen load distribution. This load distribution is the basis for static calculation in the second part of the work. The second part of the work has the intention of developing practice-oriented calculation formulas which enables the engineer already in the pre-dimensioning stage of saddle supported tanks to take the horizontal transverse load, like demanded in the ADR, into account. In addition two different computation methods are analyzed with regard to their suitability for a parameter study of the analyzed system. These are on the one hand the computation with the help of the finite elements method (fem) and on the other hand the computation on basis of an analytic computation method, which is self-depent developed further for the analyzed case. The analytic method is based on the generalised technical bending theory. Both the fem and the analytic method lead to the result that the peak stress at the saddle horn rapidly reaches the theoretical yield stress. Before making the parameter study to develop practice-oriented calculation formulas some calculation based on an elastic-plastic material behaviour are made. Therefore the van Mises’ equivalent stress criterion model is used. A parameter study follows in which the radius, the shell thickness, the contact angle between the saddle and shell, the length, the distance of the head stiffener to the saddle and the saddle rigidity are varied. The evaluation of the computation results supplies calculation formulas suitable for the hand calculation under consideration of the elastic-plastic carrying behaviour in the pre-dimensioning stage of saddle-supported cylindrical shells under horizontal transverse load. This enables the planning engineer in the future to consider the horizontal transverse load appropriately even in the pre-dimensioning stage. The research of practice-oriented questions regarding the magnitude of transverse accelerations affecting the tank, the constructional design of the saddles and the ratio of the maximum stress due to vertical load to the stress due to horizontal load finally completes the dissertation.","abstract_html":"In industry the employment of fluid and gaseous goods is widely spread.
