The knowledge of the impact and the load-bearing capacity of unstrengthened/strengthened structures is a crucial source of information about the safety of masonry buildings near deep excavations, especially in dense urban areas. Incorrect calculations made for such designs can seriously affect not only an analyzed object but also the adjacent buildings. The safety of masonry buildings can be determined by many factors that are closely related to the hazards presented during the performance of deep excavations. These factors are at first identified and then prioritized. The AHP process in the multi-criteria analysis was used to support the decision-making process related to the verification of factors affecting the safety assessment of masonry buildings in the area of deep excavations. The proper design of building structures, including the verification of the structure strengthening near deep excavations, was found to be the most significant factor determining the safety of such buildings. The methodology for proceeding with the verification of ultimate (ULS) and serviceability (SLS) limit states in accordance with the literature data, current regulations, such as Eurocode 6 and other design standards, and the know-how of the authors, described in this paper was the next stage of the discussed analysis.

In the article deals with the European safety issues of large-panel buildings from the point of view of exceeding the ULS. The proprietary assessment method was proposed under the name: Dimensional Limit States Method, which is dedicated to the assessment of the safety level in the structures of large-panel buildings. The work was based on many years of computer research conducted by the author. In the paper uses the proprietary construction model of the Wk-70 system building, presents the results for vertical reinforcement inserts.

Currently in Europe there is no uniform design code for buried flexible steel structures. In different EU countries there are different regulations concerning design methods, construction and control of such structures. This paper is an attempt at presenting the problems that need to be solved in order to prepare an uniform European Code. The thematic range of the proposed code is also outlined. The idea is based on the author’s own studies on buried flexible steel structures and design methods and codes from other countries, such as: AASHTO, CHBDC, ZTV and TRVK Bro 11. Concluding remarks contain a proposal of a committee consisting of several sub-committees that needs to be appointed in order to solve particular issues. This paper should be considered as a starting point for further discussion - it is not intended to be a “closed” proposal.
