MATRIX ANALYSIS OF CUBIC FRAMED STRUCTURES

Free vibration analysis of steel framed structures

This study based on free vibration analysis and study the behavior of framed structure under different frequency of vibration using ANSYS software and shaking table. A small scale uni-axial shaking table was prepared in laboratory, which can produce lower to moderate vibration, regarding frequency and velocity. Moment resisting framed structures constructed with connecting beam and column eleme...

A wavelet-based approach for vibration analysis of framed structures

Stiffness-based Approach for Preliminary Design of Framed Tube Structures

A parametric formulation for preliminary design of tubed-system tall buildings is presented in which some optimality criteria and practical constraints are considered. Here, a minimum compliance optimization formulation, developed by other researchers, is applied to a framed-tube structure. The tube behavior is modeled as a cantilevered box beam. Independent variable in this problem is thicknes...

Rigidly Framed Earth Retaining Structures

Structures placed on hillsides often present a number of challenges and a limited number of economical choices for site design. An option sometimes employed is to use the building frame as a retaining element, comprising a Rigidly Framed Earth Retaining Structure (RFERS). The relationship between temperature and earth pressure acting on RFERS, is explored in this monograph through a 4.5 year mo...

Ray-Model for Metal-Framed Window Structures

A ray model for transmitted field calculation is developed based on FDTD simulations [1]. The basic idea is to decompose the window structure into elements defined by two neighboring metal frames. FDTD is then used to calculate the transmitted field for a plane wave incident. A ray model can thus be constructed which contains different numbers of rays each of them has information of magnitude a...
