Mechanical and electromagnetic transverse load effects on superconducting niobium-tin performance
… an enormous electromagnetic force and very large transverse loads are applied against the strands. This large force results in a degradation of the performance of the superconducting magnets. In this thesis work transverse load experiments on sub-sized cables, have been designed to study the …

Development of new protocols to evaluate the transverse loading of mine ventilation stoppings
The transverse loading requirement for stoppings as specified in the current Code of Federal Regulations is 39 psf. This measure is based on physical testing of a freestanding wall in accordance with ASTM E 72 specifications, where the dominant parameter is the tensile strength of the sealant. A …

Untersuchungen zum Tragverhalten sattelgelagerter Zylinderschalen bei horizontaler seitwärts gerichteter Belastung
… 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 …

The Optimum design of Flat Rectrangular Concrete Plates supporting loads in Buidling structures and tests on a one-third full size experimental model
… in terms of deflection and cracking at working loads. As a result their deflections have been larger than anticipated and have caused displacements and severe cracks in masonry partitions which are being supported. In order to design any rectangular flat plate for optimum performance and economy …

Development of lightweight FRP bridge deck designs and evaluations
… and determine their adequacy under AASHTO's HS25 loading case with minimum stringer spacings of five feet. Two different multicellular decks were designed and tested during this study. Both decks had fiber volume fractions of approximately 54% and weighed 14--15 lb/ft2 of deck area. Testing was …

Development of an experiment to study the effects of transverse stress on the critical current of a niobium-tin superconducting cable
… of the apparatus designed to study the effect of transverse load on a cable composed of 36 superconducting strands (with a 3x3x4 pattern) by mechanically simulating the ITER Lorentz stress condition. The apparatus was assembled at MIT and preliminary tests at 77 K and room temperature were made to …

The effects of tensile preloads on the impact response of carbon/epoxy laminates
… configuration. Tensile preloads from near zero to approximately 60% of ultimate breaking strength were applied to specimens which were impacted at energies of 3.4, 4.5 and 6 Joules (2.5, 3.3 and 4.4 ft- Ibs). The amount of damage induced into the specimen was evaluated using …

Skewed Bridge Behaviors: Experimental, Analytical, And Numerical Analysis
… solutions for skewed thick plates under transverse load and skewed bridges subjected to truck load were developed. The thick plate solution was obtained in a framework of oblique coordinate system. The governing equation in that system was first derived and the solution was obtained using …

Structural behaviour of concrete segmental lining tunnels: towards design optimisation
… during construction neglects the sequential ring loading and TBM-lining transverse interactions, which this thesis proved to be key in the short and long term behaviour of CSLs and whose study is essential if the design and maintenance of CSL structures is ever to be optimised. This thesis …

Lateral-torsional buckling behaviour of monosymmetric steel sections formed with flange upstands
… for the elastic critical buckling study for two transverse load cases. Finite element models were then employed for the nonlinear analysis for the inelastic buckling cases. Residual stresses have not been included in the finite element models. Geometric imperfections as well as material …
