Transverse prestressing and reinforced concrete as the key to restoration of masonry arch bridges

The Behaviour of Skewed Masonry Arch Bridges

Sensitivity Analysis and Parameter Identification on historical Masonry Arch Bridges

Close to reality computation of the serviceability and load-carrying capacity of old masonry arch bridges for rising live loads is a current problem. In Germany many of such roadand railway bridges exist. Some of the most important features for applicable numerical evaluation of masonry arch bridges are a realistic structural model (very often three dimensional models are necessary), the consid...

A Parametric Study: Frame Analysis Method for Masonry Arch Bridges

The predictability of masonry arch bridges and their behaviour is widely considered doubtful due to the lack of knowledge about the conditions of a given masonry arch bridge. The assessment methods for masonry arch bridges are MEXE, ARCHIE, RING and Frame Analysis Method. The material properties of the masonry and fill material are extremely difficult to determine accurately. Consequently, it i...

Assessment of Masonry Infilled Reinforced-concrete Frames with Openings

Original scientific paper Reinforced-concrete (R/C) frames infilled with masonry wall, especially with the presence of an opening, are insufficiently explored structural elements. We have experimentally investigated influence of the opening’s type and position to the lateral response of reinforced-concrete frames with masonry infill. Correction factors, that take into account influence of the o...

Application of infrared thermography to the non-destructive testing of concrete and masonry bridges

Within recent years there has been an increase in the use of NDT methods to detect defects and anomalies in various civil engineering structures. Infrared thermography, which has been successfully used in the USA in civil engineering applications, is being increasingly applied in the UK as an NDT technique. For example, the technique is now included in the Building Regulations for the assessmen...
