Driven Then Pushed Minicone Tests in a Sand Chamber
For a general knowledge on the Standard Cone Penetrometer test and its uses the reader is referred to the work of Briaud and Miran (1991). For this study (Khalaf and Briaud, 1992) a smaller...
Piles for Marquette University Math Building
This paper presents a comparison of static pile capacity predictions using CPT cone resistance results with results of a test pile program and production pile driving. Pile capacity prediction...
Evaluation and Monitoring of Pile Performance Using Dynamic Measurements in Supporting Offshore Structures
The installation of offshore platforms into deeper waters and new environments is accompanied by an increasing uncertainty in the structure response, foundation design and performance....
Seismic Wave Propagation by Finite Differences on the Connection Machine
Seismic modeling represents a difficult numerical challenge and consumes a significant amount of CPU time on the largest available supercomputers. With the advent of massively-parallel...
The Control of Large Amplitude Liquid Sloshing with Moving Baffles
Numerical simulations of three-dimensional viscous liquid sloshing in rectangular containers were carried out using an improved volume of fluid technique in conjunction with the Navier-Stokes...
Landslide-Generated Waves in Reservoirs
This paper investigates surge waves generated by landslides in reservoirs. The Navier-Stokes equations with complete viscous conditions at the free surface are solved numerically for the...
Multiple Modes of Steady-State Slide-Rock Response
The dynamic response of free standing rigid bodies to base excitation can be quite complex, as evidenced by the five motions or modes to be considered in a two-dimensional analysis: rest,...
Screen Breakwaters
The diffraction of water waves by an offshore breakwater consisting of an infinite row of equally-spaced vertical screens is investigated theoretically. The reflected and transmitted wave...
Computation of Wind Pressures on L-Shaped Buildings
The paper refers to the numerical simulation of turbulent wind conditions around an arbitrarily-shaped building composed of two rectangular blocks. The time-averaged Navier-Stokes equations...
Computation of Flow in Ice-Covered Dune-Bed Channels
A numerical method for solution of the Reynolds-averaged Navier-Stokes equations is developed to study the flow over sand dunes in two-dimensional channels. The method is applied to calculate...
Improved Time-History Analysis for Structural Dynamics Calculations
Methods are developed to reduce the computational effort in time-history analysis of nonlinear structures. The methods permit use of much larger time intervals than are possible in conventional...
Modal Coupling Effect of Non-Classically Damping
The equations of motion of a structure in undamped modal coordinates may have non-zero off-diagonal terms in the damping matrix. Although these terms are commonly neglected, studies have...
Free Vibration Analysis of Asymmetric Buildings
A simple procedure for free vibration analysis of asymmetric buildings is presented. This method assumes that each floor is a rigid diaphragm with three degrees of freedom (two lateral...
Wave Propagation in a Nonlocal Strain-Softening Continuum
The problem of wave propagation in a nonlocal strain softening solid is first discussed analytically. It is demonstrated that 'loading' waves can still propagate in the strain softening...
Routes to Chaos of a Vertically Rotating Pendulum
Each blade of a mechanical shredder may be modeled by a pendulum whose pivot rotates in a vertical circle. The transition to chaos of small periodic motion about radial lines us the driving...
Roll-Waves on a Non-Newtonian Mud Layer
This article extends the theory of roll-waves due to Dressler (1949) to a thin layer of mud modeled as a power law fluid. Roll-waves are periodic bores moving at a constant velocity down...
Inflation Instability of Cylindrical Membranes
A new procedure which investigates inflation instability of cylindrical nonlinear membranes is developed. The general characteristics of inflation instability are described. An efficient...
Stochastic Finite and Boundary Elements
The random coefficients in partial differential equations, which govern the responses of stochastic thermo-mechanical systems, (Dasgupta, 1991), pose a computational challenge. The large...
Investigation of Parametrically-Induced Excitation in Concrete Columns
A mathematical model is developed which accounts for the non-linear material characteristic of concrete members. The axial and transverse motions of concrete columns, are found to be second-order...
Tripod Crane Concept for Lunar Surface Construction
A construction scheme using three integrated cranes is proposed. Mikulas proposed a lunar crane concept which introduces a set of three cables in order to stabilize the payload. This paper...
