Study and Renovation of Historical Masonry Arch Bridge

Abstract

The aim of this research was the investigation of the properties of clay brick masonry arch bridge materials with a purpose of finding the best methods for reconstruction and renovation of the structure. The restoration, reconstruction and upgrading of historical heritage bridges require a careful investigation of materials and causes of damages. In many cases, the use of incorrect composition of joint mortar and clayed brick may lead to unfavourable result. It is important to ensure the natural water migration in historic masonry as it should not be interrupted after restoration or reconstruction measures performed. As an example the results of investigations and upgrading of historical clayed brick masonry bridge over the Venta River in Kuldiga town in Latvia had been analyzed. During the long lifetime and pro-active maintenance polity, the bridge had a lot of damages that could affect its further service life. For geometrical data collection laser scanning method was used that ensures sufficiently accurate data for reconstruction design, as well as the information for architectural investigation. Three-dimensional scanning of the heritage structure using 3D laser scanners allows the further transformation of information into the surface mesh model. This paper presents results of the investigation, and design of restoration and reconstruction works.

Investigation of Structural Performance of Historical Amasya Hundi Hatun Bridge

“…Then the bridges' deformation patterns and crack and stress distributions are determined by performing static and dynamic analyses on the models [2,10,14,17,23,24,25]. In the second group of studies, deteriorations and deformations on historical bridges are determined through observations, and the improvement and restoration work required to eliminate these defects are examined in detail [1,16,20,21,26,40]. In one study, Altunisik, Kanbur, and Genc [6] examined the effects of varying thicknesses of arches (one of the main load-bearing elements of a historical bridge) on the structural behavior of the bridge.…”

“…(Pepi et al (2017) yaptıkları çalışmada, ağır hasarlı bir köprü üzerine geometrik araştırmalar, dinamik testler gerçekleştirmişler, köprünün sayısal modelini oluşturarak, köprünün yapısal performansını değerlendirmişlerdir. Tarihi yığma köprülerin rehabilitasyonunu ve renovasyonunu inceleyen araştırmalar (Paeglitis et. al.…”

Strengthening of Arched Masonry Structures by Additional Reinforcement: Design Approaches and Comparison to Experiments

“…This work aims to document the options available for the use of additional reinforcement in the strengthening of masonry structures loaded with the interaction of a normal force and a bending moment. The next aim is to experimentally verify the behaviour of The method of additionally inserting of non-prestressed reinforcement is one of the several methods for strengthening of vaulted masonry structures (Alecci, Misseri, Rovero, Stipo, De Stefano, Feo, & Luciano, 2016;Anania, Badalà, & D'Agata, 2013;Borri, Castori, & Corradi, 2011;Fauchoux & Abdunur, 1998;Foraboschi, 2004;Oliveira, Basilio, & Lourenço, 2010;Paeglitis, Paeglitis, Vitiņa, & Igaune, 2013;Tao, Stratford, & Chen, 2011). The presented method allows the strengthening of masonry structures without the necessity for large-scale modifications to the structure of vaults (i.e., the excavation of infill), especially in the case of external applications.…”
