Seismic design code - Part III. - Provisions for the seismic assessment of existing buildings, Code P100-3/2018

Seismic design code - Part III. - Provisions for the seismic assessment of existing buildings, Code P100-3/2018

The purpose of the code is to establish criteria and procedures for the seismic assessment of existing buildings and, as applicable, a basis for intervention work to reduce their seismic vulnerability.

The code applies to the seismic assessment of buildings and constructions with similar structures in Romania, regardless of when they were built.

The provisions of the code are harmonised with the provisions of national standard SR EN 1998-3.

The seismic assessment of structures with special functions (e.g. nuclear power plants, maritime platforms, bridges, dams, piers, chimneys, reservoirs, silos, cooling towers, etc.) is not covered by the code.

The provisions of the code may also be applied in the case of buildings that are historic monuments if they do not run contrary to the concepts, approaches and procedures covered by the specific normative documents.

The code includes provisions for the seismic assessment of existing buildings, which are used together with the provisions of design codes for other types of works carried out on structures made of different materials.

It is recommended that all buildings pre-dating the entry into force of standard P100/78, as well as those with more than five above-ground levels built in accordance with standard P100/78 or P100/81, should undergo priority seismic assessment.

For the seismic assessment, different safety factor values are necessary for materials and structures, established according to the information available and its degree of uncertainty.

The conditions established by the code are minimal and not restrictive.

The provisions of the code are intended for specialists in the construction industry (technical experts, project verifiers, design engineers), beneficiaries, investors in or owners of the buildings, local authorities and construction inspection authorities.

The code is structured as follows:

1. General information

2. Seismic assessment

3. Performance requirements

4. Information for the seismic assessment

5. Qualitative assessment

6. Quantitative assessment

7. Assessment of the foundations and the ground in which they are laid

8. Conclusions of the assessment

Annex A: Seismic hazard
