Large Deflection Buckling of Space Frames
Buckling loads of space rigid frames based on large deflection theory were determined herein by a method referred to as the constant load method. In this method, the load is maintained...

Efficient Reanalysis of Modified Structures
Techniques are examined for the analysis of structures in which the dimensions of some or all members may be changed. Several existing methods which do not require complete reanalysis...

Flexural Rigidity of Concrete Column Sections
The examination of theoretical stiffness ratios for reinforced concrete sections under uniaxial bending and axial load has shown that a reasonably simple set of approximate equations can...

Behavior of Laterally Reinforced Concrete Columns
The results of an experimental and analytical investigation of the effect of non-uniform lateral confinement, such as that produced by closely spaced rectangular ties, on the behavior...

Finite Element Analysis of Reinforced Concrete Slabs
The bending analysis of reinforced concrete slabs by the finite element method is presented. The analysis concentrates on the nonlinear behavior due to progressive cracking of a slab and...

Reticulated Space Structures
Recent developments in the application of reticulated or shell-type construction are presented. Five general methods of analysis are given: (1) the stiffness approach; (2) continuum shell...

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...

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...

Preliminary Design of Simple Rigid Frames
A better design aid for rigid frames can be developed by utilizing computer to analyze a certain frame many times. By studying trends in the computer solutions, design charts show in this paper can be...

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...

Elastic Buckling of Plate Girders from Pure Bending
The elastic buckling of stiffened web plates of girders subjected to pure bending is investigated using the theory of orthotropic plates. The curves of critical loads containing the influences...

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...
