Experimental Study of Flexural-Torsional Buckling
The results of an experimental study, 48 tests, of the flexural-torsional buckling behavior of two-span beams and rigid frames are presented and compared with the theoretically predicted...

Plastic Design of Coupled Frame-Shear Wall Structures
Many structures in the 20-story to 40-story range consist of a number of bents tied together by diaphragms at each floor level. Each bent may consist of a rigid frame or of rigid frames...

Analysis of Frames with Partial Connection Rigidity
A computer oriented method is described for the analysis of frames with partially rigid beam-to-column connections. The moment-rotation relationship for the partially rigid connections...

Prediction of Footing Vibrations
The vibrations of massive footings on soil are investigated. The experiments with bodies having variable mass and foundation base size are compared with the half-space theory. The amplitudes...

Deflections of Shallow Pier Foundations
The use of shallow pier foundations for rigid frame structures requires that the designer of the structure be able to predict any lateral spreading of the foundation so that the frame...

Dynamics of Single Point Mooring in Deep Water
The dynamics of a single point mooring of an oceanographic disc buoy with diameter of forty feet were investigated in ocean waves, current and wind for water depths in the order of 10,000...

Influence of Line Motion on Waterhammer Pressures
The large pressure increases following rapid valve closures in liquid flow pipe systems produce large forces which must be resisted by the system structure. These forces invariably produce...

Finite-Element Analysis of Skewed Shallow Shells
The support conditions used for roof shells are frequently markedly different from those necessary for analytical solution methods. Numerical methods provide the versatility to cope with...

Resilient Ferry Slip with Retractable Fender
The design of a ferry slip using retractable contact frames, moving inward and upward on bearing brackets with tracks of various inclination is described. The rigid frame on which the...

Model Study on Arching Above Buried Structures
The authors establish an analytical structural model of arching above an underground structure. The model was based on various experimental parameters, permitted analysis of the behavior...

Analysis of Plate Bending by Triangular Elements
A triangular element composed of three subelements is proposed with the use of a quadratic displacement function for each subelement. The function allows the rigid-body displacement of...

Dynamic Safety Analysis of Multistory Buildings
The response of multistory buildings to a class of nonstationary random excitation of earthquake type is obtained under the assumption that the building can be treated as a shear beam...

Frame Analysis including Change of Geometry
A method is developed of incorporating the effects of change of geometry in the analysis of rigidly jointed plane frames when using the displacement method. Where members are split into...

Dynamic Response of a Horizontally Curved Bridge
A method of analysis of the dynamic response of a simple-span horizontally curved bridge subjected to a constant moving force is presented. Differential equations for the out-of-plane...

Analysis of Unbraced Multistory Steel Rigid Frames
A compatibility method of analysis is developed for the study of the inelastic in-plane behavior of multistory steel rigid frames subject to sidesway. The method provides for the following...

Optimum Design Using Available Sections
Conventional optimum structural design methods assume that a continuous spectrum of member sizes is available to the designer. For example, in the minimum weight rigid-plastic design of...

Stability Analysis of Frameworks by Matrix Methods
A general matrix formulation for the solution of buckling loads and modes of rigid frameworks under axial loads only in the primary condition is presented. Input data for the computer...

Land-Use Intensity, the Lui Scale, and Zoning
A comprehensive data system on site planning for new residential projects has been devised, featuring a numerical scale from 1 to 10, covering all intensities of land use. The data system...

Stability of a Bar Under Eccentric Follower Force
A uniform cantilevered bar subjected at the free end to an eccentric, compressive follower force is considered. It is shown that, for cross sections having two axes of symmetry and vanishing...

Space-Framework Method for Three-Dimensional Solids
A space-framework model is derived to represent a rectangular, prismatic, solid element which is assumed to be in a state of uniform stress and which has any value of Poisson's...
