Technical Sciences
Course Leader: Vlad Petrescu
Learning outcomes:

Acquiring basic notions concerning detailing, configurating and dimensioning criteria for structural members, subassemblies and assemblies made of wider use materials. Elementary notions concerning loads take over and correct configuration of usual construction systems. Detailing and calculus of joints. Applying notions of mechanics (statics and strength of materials) for configuration and design of structural members made of timber and steel.


Technical performance conditions, performance parameters, criteria and levels of performance. Materials for structures (timber, steel, concrete, masonry). Methods for predimensioning and calculation hypothesis. Loads in constructions and structural response. Defining dead (permanent), live loads / dynamic loads.
Behaviour of structural and nonstructural members under different types of loads.
Fundamental structural members and subassemblies: linear bar elements, planar slab, solid wall. Effect of forces upon them. Choosing the structural system. Recognizing structural and non-structural members.
Trusses - detailing and calculation methods (joints isolation method, sections method).
Shape resistant structures. Arch and suspended structures. Classical types of arches. Thrust conveying problems.
Detailing and calculation of planar slab structural members.
Specific of detailing and calculation for timber structural members.
Specific of detailing and calculation for steel structural members.
Large span structures. Flexible structures. Configuration of cross sections. Preliminary calculation for members under bending with shear made of different materials (predimensioning, maximum spans, deflection limits). Failure mechanisms.
Structural columns under centric and eccentric compression. Configuration of cross sections. Preliminary calculation.
Joints for timber and steel, methods of dimensioning.
Basic notions concerning behaviour of nonstructural components, furniture and equipments under earthquake loads. Seismic response of non-restrained bodies (furniture, equipments, objects) in buildings and open public areas (interior and exterior).

Teaching Method:

Theoretical weekly courses with applications and calculation examples.


Written examination with theoretical and applicative content at the end of semester. The final mark represent an average between the examination mark (50%) and the average of the verification test of the 7-th week (30%) and of partial verifications (20%). The minimum accepted mark to pass is 5 (five). Attendance to the course is compulsory for being admitted to enter the final written examination.
