TEACHING MATERIALS | AULAWEB |

The purpose of this course is to sensitize the student to the structural design with the aid of automatic calculus code, which are used professionally both for the determination of the stress in frames, and during the verification, in terms of capacity (resistance, stiffness and ductility) of the cross sections.

The teaching aims to provide students with operational capabilities in the field of structural design, presenting methodological basis and practical tools based on computer science environments which complement the computational analysis of the structures with the automated verification, structural elements and structures design procedures. The recurrent structural design (such as multi-stories buildings in reinforced concrete) and the computational analysis of the structures (finished elements method) methodologies learnt during previous courses, are supplemented in order to develop full and computerized structural design procedures, with the purpose of providing students with useful knowledge and specific skills for their professional career.

The lessons will take place in the computer science classroom and Calculus Codes SAP2000 V.17 and VIS 9.3 will be required. The Professor will project a building for residential purposes in detail with the aid of the abovementioned Calculus Codes, in accordance with the anti seismic rules in force. The lessons will partially be (video) recorded with a specific “open source” software in order to realize “video tutorials” which will be useful to the students who will want to individually view again the Professor’s FEM modelling demonstration in class. The exercises will take place in class and will be followed by the Professor.

The automatic calculation projecting course is divided in 13 lessons, 4 consecutive hours each as follows:

**LESSON N° 1 – CALCULUS CODE INTRODUCTION**

Lesson in class conducted by the Professor with an explanation of the calculus software and its potential, focusing mainly on the modelling of bidimensional elements such as slabs loaded in their flat surfaces and inflected slabs. Modelling of a shear wall with no openings: determination of the forces and moments according to the software’s results, mesh’s thickening effects and evaluation of the results by cross referencing the exact literature solution. Modelling of the same wall with the addition of openings and considerations regarding the effects that these openings produce on its global performance.

**LESSON N° 2 – MODELING OF A MULTI-STORIES BUILDING FOR RESIDENTIAL PURPOSES**

Lesson in class conducted by the Professor in which the geometry of the developed building will be modelled and dimensioned in the Concrete class (building made of five stories + one basement). Setting of the FEM modelling, discussion of criteria and strategies for a correct definition of the numeric model, sensitizing the student towards the possibility of realizing different models (often simplified) in order to achieve reliable results, easily verifiable without wasting too much time or resources.

**LESSON N°3 – MODELING OF A MULTI-STORIES BUILDING FOR RESIDENTIAL PURPOSES**

Lesson in class conducted by the Professor in which the modelling of lesson number 2 will be completed and in which each load combination, the usage of design loads on the calculus model and the assignment of the combination of the actions will be defined.

**LESSON N° 4 – CLASS PRACTICE**

The students will be divided in groups of two people and will work in class on the project previously dimensioned during the Concrete Design course: setting of the geometric FEM model.

**LESSON N°5: CLASS PRACTICE**

The students will be divided in groups of two people and will work in class on the project previously dimensioned in the Concrete Design course: completion of the FEM mode, defining of the design loads and their combinations.

**LESSON N°6: MODELING OF A MULTISTORIES BUILDING FOR RESIDENTIAL PURPOSES**

Lesson in class conducted by the Professor in which considerations will be made regarding the correct definition of the “q” behaviour factor to apply to the response spectrum, focusing mainly on verifying the torsional deformation of the building and on the determination of the flexural and torsional stiffness. Definition of the spectrum project of an Italian municipality situated in a sensible seismic zone (Zone II or Zone I). Comparison between the results obtained by the calculus software and the ones obtained during the Concrete Design course.

**LESSON N° 7 – CLASS PRACTICE**

The students will be divided in groups of two people and will work on the project previously dimensioned during the Concrete Design course: evaluation of the building’s susceptivity to torsional deformability, definition of the project spectrum, seismic analysis of the structure and validation of the results.

**LESSON N° 8 – CRITICAL ANALYSIS OF THE FEM MODEL RESULTS AND VERIFICATION OF THE STRUCTURAL ELEMENTS**

Lesson in class conducted by the Professor in which the output of the FEM model will be “critically” analysed in terms of displacements of the control joints, stresses in the main structural elements and basic global reactions. Verification of beams and pillars with a suitable “post processing” software in accordance with the NTC2008 norm. Verification of a shear wall in accordance with the “anti seismic” criteria stated by the abovementioned norm and comparison with the rebar obtained during the Concrete Design course.

**LESSON N° 9 – CLASS PRACTICE**

The students will be divided in groups of two people and will work on the project previously dimensioned during the Concrete Design course: verification of the main structural elements with a suitable “post processing” software, verification of a shear wall according to anti seismic criteria and comparison among the rebar obtained during the Concrete Design course, setting of the calculus report.

**LESSON N° 10 – CLASS PRACTICE**

The students will be divided in groups of two people and will work on the project previously dimensioned during the Concrete Design course: completion of the previous lesson

**LESSON N° 11 – PROFESSIONAL SOFTWARE FOR THE PROJECT, THE VERIFICATION AND THE DESIGN OF STRUCTURAL ELEMENTS**

Lesson in class conducted by the Professor in which software for structures’ executive projects will be illustrated, focusing mainly on the automatic drafting of the rebar executive designs. Outlining of the utilization of the BIM method for the interactive creation of FEM models starting from architectural and plant design 3D models.

**LESSON N° 12 – PROFESSIONAL SOFTWARE UTILIZATION FOR THE PROJECT, THE VERIFICATION AND THE STRUCTURAL ELEMENTS’ DESIGN**

Lesson in class conducted by the Professor in which a bidimensional multi-stories frame will be modelled, applying the project loads/stresses (static and seismic), its verification according to the “design capacity” criteria, extraction of the rebar executive drawings and critical analysis of the automatically obtained “product”.

**LESSON N° 13 – CLASS PRACTICE**

The students will work in class on a software similar to the one suggested by the Professor during the lessons (11 and 12) realizing the modelling of a continuous beam extracted by their works on the Concrete Design course, its verification and automatic extraction of rebar executive drawings.

Lecture notes provided by the Professor and available on AULAWEB, other than video tutorials edited by the Professor during the practicing lessons.
