Composite and Prestressed Structures Course code: SPNPK | 5 ECTS credits

Basic information
Level of Studies: Undergraduate applied studies
Year of Study: 2
Semester: 3
Requirements:
Goal: Introduction to the theoretical basis and necessary knowledge in the field of composite and prestressed structures.
Outcome: Students will be able to analyze, calculate and interpret optimal solutions in the field of such constructions, create models for identified problems, use software tools that support calculation methods, present application of methods on the example of the selected problem and applicate valid standards for calculation of elements of these structures, as well as for calculation and construction of connections between structural elements.
Contents of the course
Theoretical instruction:
  1. Basics for the calculations. Material properties. Temperature effects. Bending theory of composite girder. Simplified assumptions. Short-term loads. Influence of temperature difference. Influence of shrinkage and creep - approximate calculation. Load cases in coupled structures. Division. Load markings. Free beam. Continuous girder. Mounting conditions. Continuous girder in the area of negative moment. Dimensioning of composite structures. Proof of carrying capacity. Couplings. Performance of composite structures. Composing of concrete with concrete. Composing of prefabricated beam element and subsequently concreting slab. Fracture mechanism. Composing of fresh and hardened concrete. Rules for the construction of composite columns. Steel profiled metal sheet as formwork: limit states of bearing capacity and usability. Composite panels with profiled metal sheet in buildings: rules for structural design, calculation of limit states of composite slab with profiled metal sheet. Limit usability states of composite structures: deformations in buildings, deflections and vibrations. Prestressing steel. Properties to be met by concrete used in prestressed construction, grout. Explanation of the prestressing principle. Types of prestressed concrete. Shapes of prestressed concrete elements. Prestressing force change. Loss of the prestressing force. Equivalent load from cables and calculation of cross-sectional forces. Calculation of cross sections. Usability limit states. Load limit states. Introduction of prestressing force and constructive details. Anchors, anchoring. Prestressed elements and construction.
Practical instruction (Problem solving sessions/Lab work/Practical training):
  1. Content from theoretical classes translated into practical application through exercises.
