Use of artificial intelligence for estimating cost of integral bridges

open access: yesGrađevinar, 2021
Estimation of costs is important in every phase of realisation of construction projects. However, the influence of cost estimation is the highest in early phases as it is then that the decision about accepting the job or withdrawing from the project is ...

Experimental verification of numerical model of integral bridge

open access: yesBudownictwo i Architektura, 2014
The paper presents the results of analyses of displacements for a real reinforced concrete integral bridge. The research consisted of the measurement of vertical displacement in the middle of the span and lateral displacement of the abutment.

Nonlinear Stiffness of Semi-Fixed Dowel Joints in Semi-Integral Bridges

open access: yesApplied Sciences, 2022
The semi-fixed dowel joint studied in this paper consists of a steel dowel with rubber sleeves and a rubber pad to connect the superstructure and the substructure and to support the main beam. This type of joint is suitably used in retrofitting a jointed

The effect of braking forces on displacement of integral bridges

open access: yesBudownictwo i Architektura, 2013
The paper presents  the results of numerical analyses of the lateral displacement for reinforced concrete and single span integral bridge with foundations constructed on piles. The lateral displacement due to braking forces was analysed.

Developments and Prospects of Long-Span High-Speed Railway Bridge Technologies in China

open access: yesEngineering, 2017
With the rapid developments of the high-speed railway in China, a great number of long-span bridges have been constructed in order to cross rivers and gorges. At present, the longest main span of a constructed high-speed railway bridge is only 630 m. The

Integral Abutment and Jointless Bridges [PDF]

open access: yesBulletin of the Polytechnic Institute of Jassy: Constructions, Architechture Section, 2005
Integral bridges, or integral abutment and jointless bridges, as they are more commonly known in the USA, are constructed without any movement joints between spans or between spans and abutments. Typically these bridges have stub-type abutments supported

Development of a Novel Damage Detection Framework for Truss Railway Bridges Using Operational Acceleration and Strain Response

open access: yesVibration, 2021
Railway bridges are an integral part of any railway communication network. As more and more railway bridges are showing signs of deterioration due to various natural and artificial causes, it is becoming increasingly imperative to develop effective ...

Time-bridge estimators of integrated variance [PDF]

open access: yesThe Journal of Investment Strategies, 2013
We present a set of log-price integrated variance estimators, equal to the sum of open-high-low-close bridge estimators of spot variances within $n$ subsequent time-step intervals. The main characteristics of some of the introduced estimators is to take into account the information on the occurrence times of the high and low values. The use of the high'
