Analysis of the Non-Planar Response of a Cantilever, with the Aid of Computerized Symbolic Manipulation
The nonlinear differential equations governing the static deformations of a cantilever with a tip mass are formulated and analyzed with the aid of computerized symbolic manipulation. The...
Representation of Strategic Choices in Structural Modeling
A major concern in structural modeling is the proper choice of tools to achieve stated objectives. Problem statements in structural analysis and design are usually made in fairly abstract...
Experiments on Active Structural Control Under Seismic Loads
Two control systems, an active tendon system and an active mass damper system are selected for study for possible real structural implementation. Presented in this paper are simulation...
Frequency Response Design of Controlled Structures
The installation of optimal control systems has been shown to be effective in reducing the vibration responses of structures. In addition to the effectiveness, there are many factors that...
Neural Network Approaches in Structural Mechanics Computations
The neural computing paradigm has not been extensively researched in terms of its applicability to a wide variety of structural engineering problems. At an intellectual level this research...
A Study of the Precision of Optimum Design Using Suboptimization
As the scale of structures becomes larger and their configuration become more complicated, the design variables and constraint conditions increase, and numerical calculation of the optimum...
Two-Level Optimization of Nonlinear Structures
This paper presents several optimization design problems and their applications to both cable structures and geometrically nonlinear braced-rib arches. The sum of squares of residuals...
Experience with the p-Version Program PROBE
The conventional approach in the FEM is known as the h-version, in which the solution accuracy depends on the size h of elements. The alternative approach is the p-version, in which the...
A KBES for Seismic Design of Buildings
A knowledge-based expert system for earthquake resistant design of buildings is described. The knowledge-intensive nature of the domain and the consequent motivation for an expert-system...
A Prototype Expert System for Steel Connections
A PC-based, menu-driven, five-module prototype knowledge-based system has been developed for steel connections. The system can solve various steel connection problems by utilizing the...
