Objectives

Knowledge, understanding and solving on science and structural engineering problems refer to buildings and civil engineering works.
Knowledge on:
• probability theory,
• structural safety,
• actions in buildings, load analysis and load combination to ultimate limit states.
• linear elastic analysis,
• construction materials (concrete and reinforcing steel) and acceptance procedures for the qualification.
• calculation methods with regard to verification of structural safety (Ultimate Limit States) for predominantly static loading (bending with and without axial force, shear, ect.) refer to the entire structure, or to structural members.
1. Calculation methods whit regard of Serviceability Limit State (cracking, deformation and tension)
Solving of isostatic and hyperstatic structures, assessing of internal actions.
The student must be able to reprocess and interpret understood knowledge in order to design and verify reinforced brick concrete slabs, reinforced concrete beam and column, foundations, ect..
Clear communication of understood knowledge.
Independent learning skills.

Prerequisites

Vectorial operations in plane system, active and reactive forces, kinematics and statics of rigid body and jointed systems, evaluation of support reactions, constraints and degrees of freedom, statically determinate or indeterminate systems.
Moments of areas
Static equilibrium, constraint forces, internal actions (axial force, shear force, torque and bending moment diagrams)
The principle of virtual work and statics of rigid body systems
Constitutive laws for engineering materials. Stress -strain relationship. Linear-elastic materials. Hooke's law. 

Contents

Theoretical content, essentially given in the first semester, is as follows:
Main typologies of framed constructions.
Structural design of simple stiffened, cellular or trussed beams.
Design of simple plane frames (continuous beams, shear-type frames, fixed-joint beams, vertical braced frames).
Structural design methods. Security probabilities. Loads on constructions. The main structural materials. Analysis of permanent, operational, environmental and exceptional loads. Inflence lines. Stress analysis on plane frames. Design with Ultimate or Serviceability Limit States in terms of strength (SLU-SLV) and stiffness (SLE-SLD).
Reinforced concrete structures: materials; Calculation criteria; collapse and operating conditions in phases I, II and III: axial load, simple and deviated bending, composed axial-bending, shear and torsion. Practical design and execution rules according to current technical regulations.
The application content, given in the second semester, will focus on the development of the individual design exercise on the basis of the theoretical part of the course itself.

Teaching Methods

100 hours: 58 hours lesson and 42 hours exercises 

Verification of learning

Verification of the acquired knowledge is carried out with a project-oriented exercise by the teacher and an oral exam. The design exercise, started during the classroom exercise, consists in the design of a simple framed structure, with a technical report, computational drawing and constructive charts
The oral test focuses on the subjects given during the lessons: theory and design of beams (simple, stiffened, cellular, trussed), simple plane frames (continuous beams, shear types, simple fixed-joint frames), vertical braced structures; technical theory of reinforced concrete on beams (axial force, simple or deviated beding, pressiforms, shear or torque) in phases I, II and III.
The assessment of the planning exercise is carried out by evaluating the completeness, correctness and clarity of the elaboration by:
A = 30 to 28 points; B = 27-25 points; C = 24-22 points; D = 21-18 points
The oral examination will take into account the evaluation of the planning exercise and, in answering the questions, the completeness, correctness and clarity of the responses.
