Monitoring and structural health assessment are the primary requirements for performance evaluation of damaged bridges. This paper highlights the case-study of a damaged Reinforced Concrete (RC) bridge structure by considering the outcomes of destructive testing, Non-Destructive Testing (NDT) evaluations, static and 3D non-linear analysis methods....

Full-text available
Re-life of aged load-bearing structures may be more efficient and economical than complete re-building. Nowadays, the strengthening of an RC structure can be designed using non-linear FE analysis, taking a realistic structural behaviour into account. Within the current article, this process is demonstrated in connection with the strengthening of a...

In service structures, especially the bridges are always prone to damages; as a result, they exhibit insufficient performance, both in terms of structural safety and functionality. Reliable techniques are always needed for assessment and strengthening design of structures. This research involves the retrofitting of a damaged bridge structure. Asses...
Article
Full-text available
Buckling analysis of arches is an important issue of the design of timber structures containing such structural elements. In the article an analytical and an approximate solution is proposed for lateral torsional buckling analysis of truss-braced timber arches. Application of the proposed methods was introduced by a numerical example. Critical forc...

Article
Full-text available
The assembly of conventional shear reinforcement in concrete beams is usually a time and labour-intensive process which may reduce the effectiveness of the mass production of prefabricated elements. In addition to the application of stirrups, the shear strength of reinforced concrete beams can also be increased by using fibre reinforcement. The obj...

The determination of service life of concrete structural members is an important aspect of durability design. The scope of the paper is to present an effective and easy to use method for the estimation of service life of pre-cast concrete structural members. A stochastic approach using stochastic finite element method was applied during the analysi...
Article
Full-text available
Durability design of structures is an important part of the de-sign process. A possible method for the durability design is the probabilistic approach considering changes of structural resis-tance and the load effect during a certain time period. In order to determine stochastic parameters of structural resistance as a function of time, deteriorati...

Summary The Kerepesi Ügető (racecourse) in Budapest (Hungary) was closed in year 2000 and most of its buildings were demolished except the Class II. Grandstand which was declared as a national monument. Our task was to perform a complete statical investigation for this Grandstand and to develop the methodology of the strengthening if necessary. Sta...

Full-text available
A square shaped reinforced concrete silo structure has been built in Alsózsolca, but the measured concrete strength of the silo has been found lower than the designed value. The Department of Structural Engineering (BUTE) has been assigned to examine the silo by complex analyses and to develop an appropriate strengthening strategy if necessary. The...
Article
SUMMARY In this paper, an analysis of the stochastic distribution of structural resistance of a reinforced concrete one-span girder is presented. The stochastic characteristics of the structural resistance are determined with three different methods: second-moment analysis, Monte-Carlo simulation and stochastic finite element method. The results de...

The deformational incompatibility existing between the shell and the edge beam when the edge beam is assumed 'rigid' or 'semi-rigid' could be resolved by, for example, applying a force system (i.e. appropriate and compatible displacement system) between the edge beam and the edge of the shell. As a tool aiming to remove this incompatibility, the au...

The racecourse "Kerepesi Ügetô" in Budapest was closed in year 2000 and all of its buildings were demolished except the Class II Grandstand which was earlier declared as a National Monument. Our task was on the one hand to perform the comprehensive statical investigation of this Grandstand and on the other hand the development of the methodology fo...

To facilitate the practical application of European Standards (EN) in Hungary the Department of Structural Engineering at the Budapest University of Technology and Economics was collaborating with the industrial partner SW Umwelttechnik Ltd. In frames of this collaboration prefabricated, prestressed concrete bridge girders were also developed among...
