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...

The aim of the paper is to present the influence of different reinforcement directions (horizontal, vertical and the combination of the two) on the shear resistance, failure modes and crack pattern of solid masonry walls. In order to investigate the effect of vertical reinforcement a new type of bonding of bricks was developed. The favorable influe...

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...

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...
Article
Timber joints are usually considered as perfectly pinned or stiff against rotation during the calculations of engineering timber structures. However the semi-rigid behavior the joints cannot be avoided in case of accurate calculations. In this paper the rotational stiffness and the full moment-rotational behavior of dowel-type timber joints were an...

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...
Article
Modeling timber joints it is essential to know the stiffness of the connections. In some cases the prescriptions of the standards contain only general approach without considering significant effects. The presented paper analyzes the load-slip behavior of dowel-type timber joints. A computer calculation method is presented, which is able to take in...

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
Analyzing the strength behavior of wooden materials the stresses that cause failure can be determined only in case of uniaxial compression or tension and shear parallel to the grain according to Eurocode 5. The standard does not give any data for stress pairs that are not part of the above cases. In this study the strength failure of the wood with...
Article
In this study, a calculation method is presented for wood fiber reinforced concrete. This combined material shares many favorable characteristics, such as small crack width values and great durability. However, the calculations show that the load-displacement behavior deviates from conventional timber and reinforced concrete structures. A significa...
Article
Standards dealing with the designing of timber structures such as Eurocode 5 do not make an obvious statement if the failure occurs in cases of an arbitrary multiaxial stressed state. Because of the fact that wood shares so many characteristics similar to those of composite materials, it can be analyzed as a unidirectional fiber-reinforced transotr...

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...
Article
Although brick has been used since the earliest times, the knowledge about the behaviour of masonry is al-most the least complete today. Academically established relations are applied in case of engineering of steel and reinforced concrete structures, but a significant part of the formulas of designing masonry are founded on experimental or intuiti...

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...
