Abstract

Tema ovog diplomskog rada je uporaba modernih alata u procjeni seizmičke otpornosti građevina. Koristeći Grasshopper, parametarski programski paket sadržan u Rhinoceros 3D-u, analizira se utjecaj konceptualnog oblikovanja na ponašanje konstrukcije. Rad se može podijeliti u dva dijela. U prvom dijelu provodi se analiza geometrijskih karakteristika konstrukcija prema kriterijima pravilnosti postavljenih u Eurokodu 1998-1. Najbitniji ispitani parametri su simetrija, kompaktnost, vitkost tlocrta i ekscentričnost konstrukcije. Drugi dio rada fokusiran je na optimizaciju tlocrta postojećih konstrukcija koristeći evolucijske algoritme. Cilj optimizacije je smanjenje udaljenosti između centra mase i centra krutosti tlocrta zgrade kako bi se smanjio utjecaj torzije na konstrukciju. U radu se ispituju mogućnosti i nedostaci parametarskog projektiranja te postavljaju temelji za daljnje istraživanje. Krajnji ishod je napraviti skriptu koja omogućuje brzi proračun bitnih geometrijskih parametara i optimizaciju tlocrta konstrukcija što može poslužiti kao pomoć pri preliminarnom odabiru rasporeda zidova u tlocrtu ili kao pomoć pri pojačavanju zgrada oštećenih u potresu.

Abstract (english)

The topic of this thesis is the application of innovative tools in the seismic assessment of buildings. Using Grasshopper, an addon to Rhinoceros 3D, the impact of the conceptual design on the structural behaviour of various floorplans is analysed. The paper can be divided into two distinct parts. The first part of the paper concentrates on analysing the geometrical characteristics of structures according to the floorplan regularity criteria set in Eurocode 1998-1. The most important examined parameters are the floorplan's symmetry, compactness, slenderness, and eccentricity. The second part of the paper focuses on optimising the floorplan of existing structures using evolutionary algorithms. The optimisation goal is to reduce the distance between the centre of mass and the centre of rigidity of a building’s floor plan to reduce the impact of torsion on the structure. The paper examines the possibilities and shortcomings of parametric design and lays the foundations for further research. The result is to create a script that allows quick calculation of the essential geometric parameters and floorplan optimisation of structures, which can help when choosing the preliminary layout of walls on the floorplan or aid in strengthening earthquake-damaged buildings.
