Ultimate Load Capacity of the Cable Tower of Liede Bridge
The cable tower of Liede Bridge is a double-column curved-lever arched-beam portal framed structure. Being novel and unique in structure, its cable tower differs in complexity from traditional ones. This paper analyzes the ultimate load capacity of cable tower by adopting the finite element calculations and model tests which indicate that constitutive relations applied here give a better simula...
متن کاملThe Research of Space Temperature Distribution in Solid Tower of Extra- dosed Cable-Stayed Bridge
Based on space temperature field test in solid tower of extradosed cable-stayed bridge, the method to calculate the space temperature field in solid concrete bridge tower is put forward systematically. By defining a series of meteorological parameters and concrete thermal parameters, the bridge tower temperature distribution is gotten. Compared with the experimental data, error is found within ...
متن کاملActive Vibration Control of a Bridge Tower Structure Using Filtered Lq Control Technique
A lumped modeling method and a therein based simple robust control design are proposed in this paper for controlling the multiple vibration modes of a bridge tower structure under construction. The method is specified by a physical state-space suboptimal controller, designed upon a lumped model, combined with the socalled "structure filters" and the software filters for preventing spillover of ...
متن کاملInfluence of apparent wave velocity on seismic performance of a super-long- span triple-tower suspension bridge
As one of the main characteristics of seismic waves, apparent wave velocity has great influence on seismic responses of long-span suspension bridges. Understanding these influences is important for seismic design. In this article, the critical issues concerning the traveling wave effect analysis are first reviewed. Taizhou Bridge, the longest triple-tower suspension bridge in the world, is then...
متن کاملAre boys better than girls at building a tower or a bridge at 2 years of age?
This study was designed to look at the differences in visuospatial abilities between boys and girls before they can speak fluently. At the mandatory two year follow up visit, children were given the opportunity to build a tower and a bridge. In children whose birth weight was > or = 2500 g, the capacity for erecting a tower was the same in both sexes, but for building a bridge striking differen...
