Pipeline Stability Under Finite-Amplitude Waves
The lateral stability of a bottom-laid pipeline under finite-amplitude waves which are shoaling on a mildly-sloping, rigid beach is considered. Incipient sliding motion conditions are...

Buckling of Stiffened Webs by Local Edge Loads
A finite strip method is used for analysing the buckling of longitudinally stiffened web plates subjected to transverse local edge loading. The probLem is of particular importance for...

Rigid-Body Response of Base-Isolated Structures
The problem of control of rigid body response of structural systems such as nuclear islands, which are mounted on a gird of bearings with three dimensional damping and stiffness properties,...

Rigidities of Nonorthogonally Shaped Waffle Slabs
Theoretical formulae are presented for the various rigidities of non-orthogonally shaped waffle concrete slabs for both the precracking and postcracking stages. The deduced expressions...

Motion Characteristics of Floating Structures
An engineering approach to the time domain analysis which accounts for the effects of damping is developed for the purpose of evaluating the rigid body response motion of a two-dimensional...

Edge Stiffeners for Thin-Walled Members
An effective width approach is presented for predicting ultimate strengths of thin-walled compression elements with edge stiffeners. In conjunction with procedures for predicting ultimate...

Intermediate Stiffeners for Thin-Walled Members
An effective width approach is presented for predicting ultimate strengths of thin-walled compression elements with intermediate stiffeners. The study is limited to intermediately stiffened...

Wave Forces on Rigid Pipes Using Ocean Test Data
A test pipe rig was designed, fabricated, and then placed in the ocean, offshore from Honolulu. The pipe diameter was 16 inches, its length 17.5 feet, and the water depth was 37 feet....

Optimality Criteria Method for Building Frames
An automated procedure is presented for the optimum design of large frameworks having size, stress and displacement constraints. The main feature of the algorithm is the use of a simple...

Parameter Study of Outrigger-Braced Tall Building Structures
The behavior of outrigger-braced tall building structures is studied taking into account the flexibility of the outriggers. Expressions are developed for the core moment distribution,...

Dynamic Response of Foundations with Arbitrary Geometries
A procedure is developed for determining the dynamic response of an elastic- half-space to the rigid body motion of an irregularly shaped foundation. The method is to subdivide the foundation...

Earthquake Rocking Response of Rigid Bodies
Using a computer program, the rocking and overturning response of rectangular blocks of various sizes and aspect ratios is studied under several strong motion earthquakes. The effect of...

Dynamic Behavior of Floating Storage Vessel
The response of a cylindrical floating storage tank due to small amplitude reqular waves is analyzed. The storage vessel is anchored by means of a riser connected to the ocean floor. The...

Frame-Wall Systems with Rigidly Jointed Link Beams
A new continuum model for the lateral load analysis of frame-wall systems with rigidly jointed link beams is presented. It consists of a vertical shear element with infinite flexural rigidity...

Elastic Instability of Unbraced Space Frames
Elastic instability of rigid-jointed, unbraced, single-story single-bay, orthogonal space frames subjected to static loads at the column tops is studied. The columns are assumed to be...

Torsional Rigidity of Partially Yielded I-Sections
Steel beam-columns of I-shaped cross section commonly collapse in a flexural-torsional mode. The St. Venant torsional rigidity is therefore one of the relevant section properties in analysis....

Plane Stress Analysis Using Modified Sector Element
The object of the present study is to develop a modified annular sector element (PSR element) that can give quite acceptable results even for a coarse mesh. The PSR element is developed...
