The article represents a study on the methods of calculation and evaluation of the properties of existing masonry, either by the method of testing the cores extracted from the masonry, or by the in-situ use of flat presses. The paper describes in parallel the two test methods along with the results obtained after performing them. At the same time, the method indicated in P100-3 / 2008 is analyzed by calculating the properties of the existing masonry starting from the properties of the bricks and mortar. The aim is to highlight the limitations of regulation P100-3 / 2008 in this regard. Finally, a case study on the expertise of Casa Vernescu is presented. When performing the expertise, the indications P100-3 / 2008, of annex G of P100-3 / 2008 and of the normative MP025 / 2004 were followed.

The article is an overview of the main intervention techniques currently put into practice on existing buildings. Ways to remedy the existing degradations, the need to ensure the unitary cooperation of the building and methods to improve the structural seismic capacity are treated.

The restoration and consolidation of the historical monument has become a necessity since the transformation of the building into the residence of the ambassador of the Federal Republic of Germany in Bucharest. The new function also involves the modernization of installations according to current standards, as well as the use of systems that are as environmentally friendly as possible. Thus, the technical solutions adopted to strengthen the structure, especially the seismic action, take into account in addition to the conditions of strength, stability and deformability, and the restrictions and permissiveness of intervention enunciated by the historical study and the implementation of complex and modern technologies of impact installations. significantly on the strength of existing masonry walls.

Articolul reprezintă o trecere în revistă a unor lucrări de consolidare de mare anvergură efectuate asupra clădirilor monument istoric. Astfel de lucrări prezintă dificultăți sporite, fiind necesară conservarea elementelor definitorii, cu valoare culturală deosebită. Sunt trecute în revistă consolidările Palatului de Justiție, Palatului Victoria, Palatului Patriarhiei, Librăriei Cărturești-Carusel și Bisericii Evanghelice C.A. din Sibiu.

Biserica din a suferit numeroase remedieri, lipsind însă o abordare de ansamblu asupra întregii structuri. Spre finalul anilor 2000 stabilitatea edificiului era puternic afectată, anumite elemente fiind în prag de colaps. Intervenția îmbunătățește comportarea seismică, aliniindu-se recomandărilor internaționale pentru monumente, însă nu aduce structura la normele curente de proiectare. Reabilitarea este implementată etapizat, urmărindu-se adoptarea eficientă a soluțiilor minimale de intervenție.
