Abstract

Bu çalışma, ayrık kabuk tasarımlarında form bulma, yapısal performans değerlendirmesi ve mimari form ile üretim maliyetinin eş zamanlı olarak optimize edilmesini amaçlayan uyarlanabilir bir hesaplamalı yöntem sunmaktadır. Önerilen yaklaşım, mekansal ve işlevsel gereksinimler dikkate alınarak mimari ve yapısal kısıtlar altında dengeli tasarım alternatifleri üretmektedir. Yöntem kapsamında çok amaçlı evrimsel bir optimizasyon iş akışı geliştirilmiştir. Gevşeme tabanlı form bulma süreci verilen bir başlangıç geometrisinden hareketle denge şekillerini elde ederek ahşap kaset elemanlardan oluşan bir ayrık kabuk tasarlamaktadır. Sonlu eleman analiz modeli ise deformasyon analizi ile düğüm noktalarındaki yer değiştirmeleri değerlendirmektedir. Mekansal kullanım ile ilgili ilgili mimari kısıtlar ve sistem stabilitesine ilişkin yapısal kısıtlar, karar değişkenleri ile birlikte optimizasyon sürecine entegre edilmektedir. Optimizasyon algoritması, üretim maliyetini en aza indirirken, sürekli bir mimari kabuk yüzeyinin geometrik özelliklerine yüksek benzerlik gösteren ayrık kabuk formlarını üretmeyi hedeflemektedir. Yöntemin uygulanabilirliği, iki farklı ayrık kabuk tasarım senaryosu üzerinden test edilerek uygun tasarım alternatifleri ortaya konmuştur.

A Form-Finding and Multi-Objective Optimization Approach for Discrete Shell Design Studies

Abstract

This study presents an adaptive computational technique that applies form-finding, assesses structural performance, and optimizes architectural form and production cost for discrete shell design. The approach generates design alternatives that balance objectives under architectural and structural constraints, considering spatial and functional needs. To realize the method, a multi-objective evolutionary optimization workflow is formulated. The relaxation-based design method explores equilibrium shapes corresponding to an input geometry to create a discrete shell consisting of timber cassette elements. The finite element analytical model evaluates nodal displacements through large deformation analysis. The architectural constraints related to spatial use and structural constraints regarding system stability are introduced to the optimization workflow alongside the decision variables. The optimization algorithm minimizes production cost while generating a resembling discrete approximation of a continuum architectural surface. The viability of the approach is demonstrated in two distinct cases of discrete shell design problems to create suitable design alternatives.
