Dynamic Analysis of Transmission Line Towers
The transmission line towers are one of the important life line structures in the distribution of power from the source to the various places for several purposes. The predominant external loads which act on these towers are wind and earthquake loads. In this present study tower is analyzed using Indian Standards IS: 875:1987(Wind Load), IS: 802:1995(Structural steel), IS:1893:2002 (Earthquake)...
متن کاملStability of ancient masonry towers: Moisture diffusion, carbonation and size effect
Moisture diffusion and carbonation influence the behavior of multiple-leaf ancient masonry walls, producing during centuries a redistribution of stresses from the core of lime mortar concrete to the external cladding of stiff masonry. This is likely one of the causes of long-time damage of some ancient masonry towers. With these motivations, coupled processes of moisture diffusion, carbon dioxi...
متن کاملExperimental and Numerical Analysis of a Historical Bell Tower
Abstract—In this paper, a procedure for the evaluation of seismic behavior of slender masonry structures (towers, bell towers, chimneys, minarets, etc.) is presented. The presented procedure is based on a full three-dimensional modal analyses and frequency measurements. As well-known, masonry is a composite material formed by bricks, or stone blocks, and mortar arranged more or less regularly a...
متن کاملStability of ancient masonry towers: Stress redistribution due to drying, carbonation, and creep
Extending the analysis of the evolution of pore humidity and carbonation presented in a preceding paper by Ferretti and Baz ̆ant, this paper analyzes the redistribution in time of vertical normal stresses across the multiple-leaf wall of ancient towers, using the example of collapsed Pavia Tower. It is shown that stress redistribution due to nonuniform shrinkage and nonuniform creep across the w...
متن کاملExperimental Analysis of Dynamic Effects of FRP Reinforced Masonry Vaults
An increasing interest in the preservation of historic structures has produced a need for new methods for reinforcing curved masonry structures, such as arches and vaults. These structures are generally very ancient, have geometries and materials which are poorly defined and have been exposed to long-term historical movements and actions. Consequently, they are often in need of repair or reinfo...
