Probabilistic Analysis of Interaction of Atmospheric Icing with Wind Open
Climatic actions are correlated with each other as they are generated by phenomena related to the physics of the atmosphere.However, this correlation is poorly reflected in codified rules for their combinations.This is why the partial fact…
Comparison of approaches to reliability verification of existing steel structures Open
Many existing steel structures are exposed to degradation due to corrosion or fatigue and to increasing loads. Their reliability assessment is then needed. The key question is whether a particular structure can be preserved ‘as it is’, or …
Reliability of existing reinforced concrete slabs exposed to punching shear Open
Selected standardised models for the verification of punching shear in reinforced concrete structures are applied for the probabilistic assessment of their reliability level. It appears that the models given in EN 1992-1-1 and prEN 1992-1-…
Reliability of a structure stricken by a tornado Open
A tornado may become a very dangerous climatic action for any structure, depending on the tornado intensity and extent of the structure. The origin of a tornado, its range and further activity appear to be unpredictable and completely rand…
Reliability basis for assessment of existing building structures with reference to sans 10160 Open
The principles of structural reliability are firmly established to provide the basis for structural performance as incorporated in design standards. Reliability-based procedures provide for variabilities and uncertainties that could reason…
Reliability Approaches Affecting the Sustainability of Concrete Structures Open
The most important reliability approaches affecting sustainability in construction consist of the target reliability levels, verification methods, and construction or intervention procedures. The optimum target reliability levels can be sp…
New European Document on Assessment of Existing Structures and Building Stock Open
The upcoming CEN Technical Specification (TS) on assessment of existing structures and building stock is related to the fundamental concepts and requirements of the current generation of EN Eurocodes. The final draft of the Technical Speci…
Reliability Verification of an Existing Reinforced Concrete Slab Open
The submitted contribution provides background information on the principles accepted in the CEN Technical Specification (TS).The application of the verification methods provided in the TS is clarified by an assessment of a reinforced conc…
THE EFFECT OF PORE DISTRIBUTION IN HISTORIC MASONRY ON THE GROUTING METHOD AND GROUTING MIX SELECTION Open
The NAKI II DG16P02M055 research project incorporates extensive experimental and theoretical research into the effect of grouting on the physical and mechanical characteristics of brick, stone and mixed masonry. The focus of the research i…
ECONOMICALLY OPTIMUM STRUCTURAL DESIGN: METHODOLOGY AND CASE STUDY Open
Codes of practice aim to assure structures have acceptable risks to the public and the minimum total costs over the working life of a design.However, current codified criteria for structural design correspond to a broad range of reliabilit…
TOWARDS OPTIMUM DESIGN FOR CRACK WIDTH LIMIT STATES: THE NEED FOR FURTHER DEVELOPMENTS Open
Serviceability limit states including cracking are of increasing importance and often dominate the design of reinforced concrete structures.Furthermore, actual crack widths and their shape play an important role in the assessment of servic…
Assessment of existing civil engineering structures Open
The upcoming CEN Technical Specification (TS) on assessment of existing structures is to be related to the probabilistic concepts and fundamental requirements of the EN Eurocodes. The document should concern all types structures made of co…
Target reliability of civil engineering structures Open
The structural reliability recommended in Eurocodes and other international documents vary within a broad range, while the reference to the failure consequences and design working life is mentioned only very vaguely. In some cases the targ…
Human safety criteria for risk-based structural design Open
Risk and reliability criteria are well established in many industrial sectors such as the offshore, chemical or nuclear industries.Comparative risk thresholds have been specified to allow a responsible organization or regulator to identify…
PHYSICAL AND MECHANICAL CHARACTERISTICS OF BUILDING MATERIALS OF HISTORIC BUILDINGS Open
The article presents partial results of laboratory research into physical and mechanical characteristics of materials most commonly used as walling units in masonry structures of historic and heritage buildings. Core boreholes and specimen…
Reliability required for heritage structures Open
The required reliability levels recommended in national and international documents for new and existing structures vary within a broad range, while the reference to relevant costs and failure consequences is mentioned only very vaguely.Th…
Reliability and Risk Acceptance Criteria for Civil Engineering Structures Open
The specification of risk and reliability acceptance criteria is a key issue of reliability verifications of new and existing structures. Current target reliability levels in standards appear to have considerable scatter. Critical review o…
