Lattice modeling and testing of aerated autoclaved concrete infilled frames

Significant infill wall damage in reinforced concrete frame buildings was observed in the past earthquakes. A vast number of numerical approaches have been proposed to estimate the non-linear behavior of infilled frames at different scales. Mesoscale lattice models were successfully used in the past to simulate the behavior of reinforced...

Stress topology analysis for porous infill optimization

The optimization of porous infill structures via local volume constraints has become a popular approach in topology optimization. In some design settings, however, the iterative optimization process converges only slowly, or not at all even after several hundreds or thousands of iterations. This leads to regions in which a distinct binary...

Open Building and User Agency: Early and Contemporary Experiments in the Netherlands

This chapter discusses the notion of ‘Open Building’ through its conceptualisations and implementations in the Netherlands since the 1960s until today. It focuses on the place of dwellers’ agency in the development of residential open buildings to investigate the potential of users’ empowerment. <br/><br/>The ‘Open Building’ approach synthesises...

Feasibility and Affordability in Brazilian Social Housing according to the Open Building Approach: An Architectural Prospection

This paper presents results of an architectural research regarding public Brazilian social housing production. Its goal was to evaluate the design, technological-constructive, economic and management feasibility of producing, as well as the financial feasibility for dwellers to access a more adequate dwelling, in light of the Open Building...

Homogenization-based stiffness optimization and projection of 2D coated structures with orthotropic infill

This paper concerns compliance minimization and projection of coated structures with orthotropic infill material in 2D. The purpose of the work is two-fold. First, we introduce an efficient homogenization-based approach to perform topology optimization of coated structures with orthotropic infill material. The design space is relaxed to allow...

Human Health and Well-Being in Relation to Circular and Flexible Infill Design: Assessment Criteria on the Operational Level

This paper addresses the connection between circular building design and residential health and well-being. The general research objective is to determine assessment criteria for the performance of indoor partitioning products in a circular model. The overarching aim is to establish a more integrated and inclusive approach to the transition from...

Current and future trends in topology optimization for additive manufacturing

Manufacturing-oriented topology optimization has been extensively studied the past two decades, in particular for the conventional manufacturing methods, for example, machining and injection molding or casting. Both design and manufacturing engineers have benefited from these efforts because of the close-to-optimal and friendly-to-manufacture...

Minimum compliance topology optimization of shell–infill composites for additive manufacturing

Additively manufactured parts are often composed of two sub-structures, a solid shell forming their exterior and a porous infill occupying the interior. To account for this feature this paper presents a novel method for generating simultaneously optimized shell and infill in the context of minimum compliance topology optimization. Our method...

Adaptive efficient global optimization of systems with independent components

We present a novel approach for efficient optimization of systems consisting of expensive to simulate components and relatively inexpensive system-level simulations. We consider the types of problem in which the components of the system problem are independent in the sense that they do not exchange coupling variables, however, design...

Composite hollow core vaults: An analysis of the Fusee Ceramic System and the design of form-active environmental friendly roofs

This thesis analysis the structural design of cilindrical Fusee Ceramique roofs and the effect of the ceramique infill elements for the time dependent deformations, stiffness and load bearing capacity, including second order. To save the few remaining buildings for the coming generations the possibilities to strengthen and stiffen these...

Thin Concrete Barrel Vault

The paper presents the structural design of a thin barrel vault constructed with Fusée Ceramique infill elements. The load transfer is analyzed and validated. For the structure composed of Fusée Ceramique elements, steel and concrete the stresses are calculated and compared to the stresses given in the codes used from 1950 to the present. The...

Structural aspects of vaults constructed with infill elements

This paper describes for the Fusée Ceramique vaults the effect of the time dependent deformations concerning the load transfer. Especially the creep and shrinkage of concrete will change the distribution of the loads acting on a Fusée Ceramique vault considerately. Recommendations for infill elements will be given to optimise the load transfer...
