Abstract This research outlines a case study for the structural rehabilitation of a historic masonry arch bridge. The major part of the railway bridge was destroyed due to high flood. The remaining parts were evaluated from structural point of view. A detailed investigation for the historic and current state of the bridge was performed. A precise description for the structural system, main elements, method of construction, materials used, and internal component was done. Also, 3D finite element analysis was conducted for the proposed rehabilitated bridge in order to identify the level of internal stresses in different structural components of the arch bridge under the effect of dead loads, live loads, wind loads, seismic loads, water flow rate, and temperature changes. The results of the finite element modeling together with the structural studies and investigations were used to develop structural guidelines for the rehabilitation project taking into account the proposed new usage as a historic walkway and the hydrological requirements as a structure over flood flow channel.

Masonry Arch Bridge

Masonry arch bridges with unequal spans are outstanding kinds of masonry bridges which are widespread in historic countries spatially in Iran. The differences in dimension of arches which mostly lead to formation of curve shaped decks in such bridges, brings a particular architecture for masonry arch bridge. However the elements which bring different lengths and heights for spans have not yet been studied. In this research by geometrical and structural survey on Khan Bridge, a kind of multi unequal span bridge in south west of Iran, it is demonstrated that especial conditions of the case lead to formation of its architecture. It is illustrated that shape of river bed, hydraulic and geotectonic factors and structural stability, are of paramount importance in terms of featuring the architecture of multi unequal span bridges with curve shaped deck.

Collapse Process

The capacity that computer can solve more complex design problem is gradually increased. Progressive collapse simulation of masonry arch bridge needs a breakthrough in the current development limitations and then becomes more accurate and integrated. This paper proposes a theoretic framework and finite element implementation on progressive collapse simulation of masonry arch bridge. It is intended to develop a new large deformation element in OpenSees, which can be used for analyzing the collapse process of masonry arch bridge. A mathematical method for large deformation element is put forward by large deformation element. The feature model for bridge structure allows families of bridge components to be specified using constraints on geometry and topology. Geometric constraints are established in bridge components by feature dependence graph in the feature model for bridge. A bridge collapse simulation software system was developed according to such combined technologies. Results from our implementation show that the method can help to simulate the progressive collapse process of masonry arch bridge.

This study aims to investigate modal parameters such as mode shapes, natural frequencies and damping ratios of a reduced scale one-span historical masonry arch bridge constructed in laboratory conditions by performing numerical and experimental analysis. Sarp Dere historical masonry bridge, in Ordu, Ulubey, has 15.5m in length and 4.75m in width was chosen as a prototype model. The reduced-scale bridge model and structural details were carried out in the scale of 1:12.5. Operational Modal Analysis (OMA) technique was used for experimental study. The experimental modal parameters of the bridge model were figured out by using Enhanced Frequency Domain Decomposition (EFDD). ANSYS software was used to create 3D finite element (FE) model and to expose the analytical modal parameters of the reduced-scaled bridge model. Moreover, FE model of the reduced-scale bridge model was calibrated based on the experimental results by using the Response Surface based FE model calibration technique to obtain more accurate results. The analysis results of experimental, initial and calibrated FE model were compared. It is noted that there are significant differences between the modal parameters obtained from experimental and initial FE model. Model calibration techniques are beneficial to get a more reasonable FE model.

Masonry Arch Bridge

The Clemente Bridge is a multi-span masonry arch bridge built during the 18th century on Savio River in Cesena. The aim of this paper is to assess its static capacity under live loads prescribed by Italian Standards in force. The analysis is performed employing RING 3.0, a computational tool based on Limit State Analysis. This method allows to individuate the minimum adequacy factor, that is the multiplier on vehicle loads required to cause collapse. In this way, a first assessment on the bridge safety can be obtained.
