Direct Design Of A Portal Frame, Angel Fajardo Ugaz May 1971

Direct Design Of A Portal Frame, Angel Fajardo Ugaz

Dissertations and Theses

This investigation was undertaken to develop plastic design aids to be used in the direct design of optimum frames. It uses the concept of minimum weight of plastically designed steel frames, and the concept of linear programming to obtain general solutions. Among the special characteristics of this study are: A. The integration of both gravity and combined loading conditions into one linear programming problem. B. The application of the revised simplex method to the dual of a parametric original problem. C. The application of A and B above in the development of design aids for the optimum design of symmetrical …


Fastener Strength In Diaphragm Braced Members, Amir Simaan, George Winter, Teoman Peköz May 1971

SUMMARY In conjunction with research projects on diaphragm-braced members conducted at Cornell University, this investigation deals with the function of the fasteners in the braced system. In these systems, the diaphragm resists the lateral deflections of the braced members, in its plane, by virtue of its shear regidity (Qdr) and its shear strain capacity Yd (as a measure of strength). Considering the system in a slightly deformed shape, compatibility of displacements and forces between the diaphragm and the braced member at their connection locations, implies that the fasteners at these locations are subjected to the action of a system of …


Static And Dynamic Buckling Of Shallow Arches, David D. Loendorf Feb 1971

Static And Dynamic Buckling Of Shallow Arches, David D. Loendorf

Civil & Environmental Engineering Theses & Dissertations

The static and dynamic buckling behaviors of a shallow, simply supported sinusoidal arch subjected to both a uniformly distributed step pressure load and a purely impulsive load are considered. Five equilibrium paths are obtained for the arch under static loading conditions. Critical static loads corresponding to two different instability modes and based on characteristics in the load displacement curve are obtained numerically. Critical dynamic loads, corresponding to three different instability modes, are obtained from a numerical procedure in which buckling criteria are based on characteristics in the time response of the structure. The influence of damping on the various dynamic …


Damping Capacity Of A Model Steel Structure, Dixon Rea, R. W. Clough, Jack G. Bouwkamp Jan 1971

Damping Capacity Of A Model Steel Structure, Dixon Rea, R. W. Clough, Jack G. Bouwkamp

CCFSS Library (1939 - present)

The damping capacities of seven model steel structures, each consisting of a heavy steel platform supported on four columns, have been determined from forced vibration tests. The vibrations were produced by an eccentric-mass vibration generator, and the amplitudes ranged from small displacements up to slightly greater than yield displacement. The tests were terminated at the higher amplitudes once fatigue cracks formed in any of the joint welds in the columns. For vibration amplitudes up to a critical amplitude slightly less than yield displacement, the damping factors of the structures were constant, independent of amplitude, and ranged between .15 and .25~ …

Analysis Of Light Gage Steel Shear Diaphragms, Albert R. Ammar, Arthur H. Nilson

CCFSS Library (1939 - present)

INTRODUCTION: It has long been recognized by structural engineers, that light gage steel cladding floor and roof decking systems have a considerable stiffening and strengthening effect on building frameworks. The beneficial contribution of these diaphragm systems is most pronounced when the structure as a whole is subjected to loads which result in an in-plane shear action of the cladding. This occurs, for example, when the rigidity of a floor or roof diaphragm acting as a membrane is utilized to transmit lateral forces to stiff end walls. Another example of diaphragm action is found in pitched roof portal sheds under vertical …
