A Force Method Model for Dynamic Analysis of Flat-Sag Cable Structures

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Approximate Dynamic Analysis of Structures for Earthquake Loading Using FWT

Approximate dynamic analysis of structures is achieved by fast wavelet transform (FWT). The loads are considered as time history earthquake loads. To reduce the computational work, FWT is used by which the number of points in the earthquake record are reduced. For this purpose, the theory of wavelets together with filter banks are used. The low and high pass filters are used for the decompositi...

Numerical Analysis of Cable Structures

Cable this structural element known since prehistoric times perhaps – was for many years used exclusively for mechanical engineering purposes. It has penetrated the civil engineering at the end of the 19th century thanks to the progress of the bridge engineering. [1]. Its excellent flexibility (and its related zero bending moments) and strength enable it to span very long distances with minimal...
