The existing structures object of demolition were in their turn inserted in a context structure composed of elements belonging to two adjacent buildings, in particular the support beams of the glass blocks are in simple support on the beams of these buildings so as to transmit only vertical loads.<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.9.9″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/teleios-ing.it\/wp-content\/uploads\/2021\/07\/cassa-di-risparmio-di-cento-pianta.jpg” title_text=”cassa-di-risparmio-di-cento-pianta” align=”center” _builder_version=”4.9.11″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.9.7″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.9.7″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.10.7″ _module_preset=”default” hover_enabled=”0″ global_colors_info=”{}” sticky_enabled=”0″]<\/p>\n The level of knowledge of the existing structures was provided by structural and calculation drawings related to the area of intervention from which it was possible to obtain the necessary information to detect the main geometric characteristics and constraints of the elements to be demolished, as well as information related to the analysis of loads. The original structure project dates back to 1970. The new structures follow the existing load warps therefore the veils 2-3-4 have orthogonal warps compared to the veil n.l. The constraint systems are similar to the existing ones therefore all the veils have the three prevented translations on one end and a free translation along the warp on the other end. The canopies are made with Monier type trusses, placed at a constant distance between centres equal to l.30m in the direction of the warping, and transversal elements having a stabilizing and architectural function to create a square mesh of 1.30x l.30m. On the planimetric mesh of the trusses are obtained the areas occupied by the glazing of the veils and the blind areas made of corrugated sheet metal floors and cast collaborating for a total thickness of 90mm. The blind parts constitute transversal stiffening and constraint for the upper beams of the trusses.<\/p>\n [\/et_pb_text][et_pb_image src=”https:\/\/teleios-ing.it\/wp-content\/uploads\/2021\/07\/cassa-di-risparmio-di-cento-sezione-a.jpg” title_text=”cassa-di-risparmio-di-cento-sezione-a” align=”center” _builder_version=”4.9.11″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][et_pb_image src=”https:\/\/teleios-ing.it\/wp-content\/uploads\/2021\/07\/cassa-di-risparmio-di-cento-sezioni-bcde.jpg” title_text=”cassa-di-risparmio-di-cento-sezioni-bcde” align=”center” _builder_version=”4.9.11″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][et_pb_text admin_label=”3.

Il progetto struttura le originario risaliva all'anno 1970. Le nuove strutture seguono le orditure di carico esistenti pertanto i velari 2-3-4 hanno orditure ortogonali rispetto al velario n.l. I sistemi di vincolo sono analoghi a quelli esistenti pertanto tutti i velari hanno le tre traslazioni impedite su un'estremit\u00e0 ed una traslazione libera lungo l'orditura sull'altra estremit\u00e0. I velari sono realizzati con capriate tipo Monier, poste ad interasse costante pari a l.30m nel verso dell'orditura, ed elementi trasversali aventi funzione di stabilizzazione ed architettonica per creare una maglia quadrata da 1.30x l.30m . Sulla maglia planimetrica delle capriate sono ricavate le aree occupate dalle vetrature dei velari e le aree cieche realizzate con solai in lamiera grecata e getto collaborante per uno spessore totale di 90mm. Le parti cieche costituiscono irrigidimento trasversale e vincolo per i correnti superiori delle capriate .<\/p> [\/et_pb_text][et_pb_image src=\"https:\/\/teleios-ing.it\/wp-content\/uploads\/2021\/07\/cassa-di-risparmio-di-cento-sezione-a.jpg\" title_text=\"cassa-di-risparmio-di-cento-sezione-a\" align=\"center\" _builder_version=\"4.9.11\" _module_preset=\"default\" global_colors_info=\"{}\"][\/et_pb_image][et_pb_image src=\"https:\/\/teleios-ing.it\/wp-content\/uploads\/2021\/07\/cassa-di-risparmio-di-cento-sezioni-bcde.jpg\" title_text=\"cassa-di-risparmio-di-cento-sezioni-bcde\" align=\"center\" _builder_version=\"4.9.11\" _module_preset=\"default\" global_colors_info=\"{}\"][\/et_pb_image][et_pb_text admin_label=\"3.

The guiding criteria for the design of the new structural elements were as follows:
1. Respect for the existing structural design in terms of constraints and load bearing arrangements;
2. Use of significantly lighter structures in order to achieve a seismic improvement assessable with the reduction of seismic masses equal to 40% at the level of the roof.<\/p>\n
1. Velario n.3<\/strong>: average light of the main trusses is about 12.20m; light of the transversal trusses is about 10.40m;
2. Velario n.1<\/strong>: average light main trusses equal to 11.SO m plus a cantilevered portion beyond the beam in e.a. equal to l.SOm about; light transverse trusses equal to 7.80m about. The structural scheme of the main truss is simply supported beam with an overhang at one end similar to the existing structure scheme.
3. Velario n.4<\/strong>: medium light trusses main equal to 11.SOm approximately; light trusses transverse equal to 2.60m approximately;
4. Velario n.2<\/strong>: average light main trusses equal to 8.20m about; light transverse trusses equal to 2.60m about.<\/p>\n
The structural analysis and the current checks on the profiles have been carried out using the Win-Strand 2009 calculation code produced by ENEXSYS S.r.l. Via Tizzano 46\/2 Casalecchio di Reno (Bologna) and the post-processor dedicated to steel structures called Win AciVer. The calculation method used was the limit state method according to DM 14\/01\/2008.<\/p>\nINTERVENTO DI RISTRUTTURAZIONE EDILIZIA PRESSO LA SEDE DELLA CASSA DI RISPARMIO DI CENTO S.P.A.

I criteri guida per la progettazione dei nuovi elementi strutturali sono stati i seguenti:
1. Rispetto della concezione strutturale esistente in termini di vincolamenti ed orditure di carico;
2. Impiego di strutture notevolmente pi\u00f9 leggere al fine di conseguire un miglioramento sismico valutabile con la riduzione delle masse sismiche pari al 40% a livello della copertura.<\/p>
