BUILDING SECTOR

Studio TEV, with the team of structural engineers that conduct stress analysis considering static and dynamic stress status, is able to guarantee, through simplified FEM calculation models, support for the following types of structures:

  • Structures in reinforced concrete
  • Wooden structures
  • Masonry structures
  • Pre-compressed structures
  • Tensile structures and ropes
  • Historical buildings
  • Restructuring and static consolidation
  • Bridges and underpasses
  • Foundations
  • Pushover analysis

The structural engineering sector is main resources of firm and the most of orders it has been obtained. The ability to design stable buildings that are resistant to natural forces combinations through the use of materials and solutions with the highest cost / quality ratio is the essence of structural engineering.

 

SISMIC ANALYSIS

Seismic analysis is useful for obtaining information on building characteristics regarding earthquake resistance. Seismic analysis is needed to identify structural interventions to be implemented for seismic adaptation or improvement.

Studio TEV offers the Seismic Vunerability Verification Service in compliance with the regulations in force (Ordinance of the President of the Council of Ministers 3274/2003 and Decree of the Head of Department of Civil Protection 3685/2003) declined in modular form according to the classification in Levels 0, 1, 2 described by the regulations.

In fact, the law defines three levels of data acquisition and verification, to be used according to the level of priority and the characteristics of the work in question. The first level (Level 0) provides the acquisition of general data on the Opera, has statistical character and applies to all Types of Opera. Subsequent levels (Level 1 and Level 2) apply to the Strategic or Relevant Works, and provide a seismic verification of this.

VERIFICATION PROCEDURE

The verification procedure begins with a look at the knowledge and the visual relief of the structure; all the information and documentation available on the property, on the site, on the construction date and on any subsequent transformations (overhangs, extensions, structural changes) are collected.

The activities for Level 0 Seismic Checks can be summarized as follows:

  • Acquisition of documentation: project structures, relationship with ultimate structures, static testing and related attachments and any photographic documentation
  • Documentary checks based on the complexity of the building
  • Surveying room for checking the congruity between the project and the actual state of affairs

Depending on the morphological characteristics of the structure and the degree of seismic hazard of the site, it may be necessary to perform Seismic Checks of Level 1 and Level 2.

  • Level 1 Seismic Checks consist of Linear Seismic Vulnerability Analyzes and are performed on Buildings and Works considered to be of high priority but that can be defined as regular
  • Level 2 Seismic Checks consist of specific Seismic Vulnerability Analyzes and after Level 1 Checks on High Priority Buildings and Works that have been assigned to S1 or S2 soil categories or are carried out close to Crusts, crests or frangible bodies.

At the end of these activities, Studio TEV issues a Level 0, 1 or 2 Seismic Verification Report with graphic and photographic attachments, containing the results of the verifications carried out and indications of the seismic vulnerability of the Opera and its actual Compliance with the safety requirements of the applicable standards.

The Report encloses the summary document to be submitted to the Presidency of the Council of Ministers / Department of Civil Protection, in accordance with the provisions of OPCM 3274/2003.

STATIC TESTING

Static testing of a building consists of a careful and careful control of the structure, with particular attention to the most static constructive elements and a structure check in its overall behavior.

Decree no. 380 and Ordinance 3274 make the Static Testing in Work Course compulsory, in accordance with the delegated modalities and timings entirely delegated to the Sensor of the Appraiser.

Studio TEV offers the service, in the manner described in art. 9 and 9.1 of Dec. Min. Of 14/01/2008, static testing of structures.

 

DIAGNOSTIC ANALYSIS OF LOAD ELEMENTS STRUCTURAL ELEMENTS

Studio TEV offers the structural diagnosis service to assess whether a particular building can continue to perform its functions in relation to the intended use. Diagnostic Surveys are useful for obtaining information about the building’s characteristics and, depending on the degree of creativity, assessing the incidence of possible disruption of the static integrity of the individual structural elements, suggesting a corrective action program aimed at the client Limit and resolve, gradually, the related issues.

VERIFICATION PRECEDURE

Legislation requires, prior to any assessment of the security of structures, the acquisition of data by a preliminary stage. This important phase involves the acquisition of project documents deposited or coming from other historical sources believed to be reliable.

At this stage, the geometric and structural direct architectural surveys are complemented by material tests for the evaluation of mechanical compression properties of concrete (Sclerometric tests, Pull-out test, Prove Lok test, Cylindrical samples sampling) and Armor delivery (direct tests; pacemometers).

Following is the theoretical phase in which the most adapted calculation model is identified to simulate the behavior of the structure, we identify and estimate the workloads with distinction between structural permanent, permanent and variable permanent as defined by current legislation, the combinations of load; And the resistance and deformability is as determined by the regulations.

Finally, load tests are carried out with the aim of verifying the carrying capacity of the structure in question by comparing the arrows obtained experimentally with those derived from calculation. Following the loading test carried out by a certified laboratory, a detailed Technical Report with all the aspects of analysis and verification developed is drafted. The report will also contain the justification for the conducted diagnostic test (on-site and laboratory tests), a comprehensive assessment of the consistency status, and an attachment to the test load report provided by the laboratory that performed it.
