Prefabricated single-storied concrete assembly hall is roofed with prestressed lattice girders, skylights, purlins and roof slabs. Significant problems of a roof structure were found out. The method and results of examination and the principles of reconstruction are described.

This paper describes an investigation of historical timber members of roof structure at Masaryk railway station in Prague. In the paper is also presented an experiment, which deals with the influence of mechanical damage to timber members in the interpretation of the results of non-destructive measurement.

This paper reports the results of research, which is aimed at determining the formation and development of cracks from rheological processes at an early age in various types of concrete. Individual recipes differ in the value of the coefficient of water and also the type of fibers.

The paper deals with the development of the magnetic method using permanent magnets for monitoring the distribution of fibers in hardened steel fiber-concrete structures and comparative measurements on test samples.

This paper deals with methods for determining the reliability of historical wooden structures and tries to outline the progress and shift in the methods used, problems or gaps in knowledge and research needs associated with this activity.

Wood is an organic material and therefore often considered to have a short lifetime. However, in the past, people did not distinguish between durability of wood and durability of masonry, proof of which is the existence of constructions that combine the use of both. In fact, the lifetime of wood can be high if specific rules are followed when designing the construction.

This paper describes the method for calculating the amplification of curved brick construction with composite reinforcement and compares this procedure with reinforcement made by conventional methods to gain a practical demonstration of the bent beam.

This paper presents an analysis of the behaviour of wood when using the diagnostic tool for "in-situ" assessment of wood based on the principle of mechanical resistance to penetration tool (mandrel) into the wood. The aim was to describe the degree of deformation and failure mode during penetration (diameter 2.5 mm) into wood in a purely radial direction and to compare the tool with a standard measurement unit testing on samples.

Wood-destroying insects is one of the biological wood pests. Attacks the wood material, both individually and also in parallel with other decaying biological pests. Knowledge of principles for the design and implementation of a hot air disposal of wood-destroying insects is necessary for the reconstruction of historic buildings. Carefull consider from a conceptual point of view is necessary for the design for redevelopment of wooden elements affected by wood-destroying insects.

This paper deals with the influence of addition of fine-grained ceramic body which was added to the lime mortars in the amount of 0–50 % of the binder weight. The addition effect of the fine-grained ceramic body on the properties of the modified lime mortars was evaluated on base of the strength and absorbency characteristics of the modified lime plasters. The ceramic body was analyzed prior to its use in the mortars. Pozzolanic activity and mineralogical composition were determined. The results showed that the addition of the ceramic body in the modified lime plasters had positive influence on their properties. The strenghts of the modified lime plasters were increased and the absorbency was reduced.

Relatively frequent request when conducting construction surveys of historical constructions is to determine the origin and age of bricks as well as their physico-mechanical properties in the context of a static evaluation of the brickwork. This article addresses this issue using an example of historic brickwork in a bridge construction.

An amendment of the Building Act will bring many changes to developers and building offices. Procedures of the Building Act will be simplified in a lot of cases. Some parts of the Building Act are modified in detail. This amendment has been published in the Collection of Laws under No. 350/2012 Coll .. and it will be effective from January 1, 2013.

The article describes unbiased comparison between two different methods of building protection against subsurface water and moisture – the foundation structure of waterproof concrete and waterproofing envelope based on the bitumen or plastic continuous sheet water proofing. The confrontation of properties and risk factors of the methods is made from the perspective of waterproof concrete structure which is the main content of the article. The comparative analysis is supplemented with the photos from field surveys and the results of independent laboratory tests.

Explosion effects belong to the category of accidental actions. During the use of building or during its construction may occur only exceptionally. ČSN EN 1991‑1‑7 (73 0035) requires to consider this type of actions and the solution of structural design to withstand the accidental action.

This paper deals with the quality of work performed concrete structures and acquaints readers with a quick method to verify the quality of the surface layer of concrete. The method indirectly points to the durability of the resulting concrete structure and the quality of work performed.

Cracks in industrial concrete floors with top layer of mineral granules are quite common. Their evaluation depends largely on the subjective opinion of the assessors. It is not the exception that the cracks appear after a longer time in the order of weeks to months after the construction. At the time up to three years after construction there is a tendency of their expansion. Cracks have a major impact on the life of industrial concrete floors.

Cross laminated timber is likely to happen in the near future, the most important product in solid wood construction in residential and high-rise construction. Depending on the size of the used components and their mutual orientation can produce a wide range of products.

This paper deals with the issue of comparing simulations for steady and unsteady thermal state at the massive structures. In this paper, computer simulations are compared with real measurements and measurements of climatic data. The evaluation showed that the steady-state temperature can be comparing with real model used after the end of the accumulation phase. It is evident that the requirements for the temperature factor of the internal surface of the solid structures, set by legislation, are a safe assumption.
