Designing Dutch tunnel ventilation systems dominated by an uncertain fire scenario

van der Drift, Sophie (author)

Adequate mechanical ventilation serves as the first and most important life-saving appliance during a tunnel fire. The most severe threat during a tunnel fire is the smoke. Most victims get incapacitated by the smoke, after which they decease from intoxication and/or suffocation. By means of mechanical ventilation, smoke-free escape routes via...

A Multidisciplinary Computational Framework for Topology Optimisation of Offshore Helidecks

Khosroshahi, Siamak Farajzadeh (author), Masina, M. (author), Antonini, A. (author), Ransley, Edward (author), Brownjohn, James Mark William (author), Dobson, Peter (author), D’Ayala, Dina (author)

Maintaining offshore steel structures is challenging and not environmentally friendly due to the frequent visits for inspection and repairs. Some offshore lighthouses are equipped with carbon steel helidecks fixed onto their lantern galleries in the 1970s to provide easy and safe access to maintenance staff and inspectors. Even though the...

Efficient computation of states and sensitivities for compound structural optimisation problems using a Linear Dependency Aware Solver (LDAS)

Koppen, S. (author), van der Kolk, M. (author), van den Boom, S.J. (author), Langelaar, Matthijs (author)

Real-world structural optimisation problems involve multiple loading conditions and design constraints, with responses typically depending on states of discretised governing equations. Generally, one uses gradient-based nested analysis and design approaches to solve these problems. Herein, solving both physical and adjoint problems dominates...

The Topology Optimised Glass Bridge

Koopman, Daan (author)

This research investigates how to design a glass pedestrian bridge that is structurally optimised for multiple load scenario’s and feasible in terms of fabrication and construction. Linear glass elements such as panes have limited freedom of shape. On the other hand, cast glass can be produced into any shape possible. When glass is used in large...

Generative Solar-Climatic Configuration: A model for feed-forward optimization of building envelopes as to solar energy potential

FLOROU, Anastasia (author)

The typical solar energy potential simulation workflows used in the AEC industry require an abundance of information regarding the detailed geometry and materialization of the design. These requisites render them incompatible with early-stage design decision-making pertaining to form-finding. By performing solar energy potential simulations at...

Topology optimisation for large-scale additive manufacturing: generating designs tailored to the deposition nozzle size

Fernández, E. (author), Ayas, C. (author), Langelaar, Matthijs (author), Duysinx, P. (author)

Additive Manufacturing (AM) processes intended for large-scale components deposit large volumes of material to shorten process duration. This reduces the resolution of the AM process, which is typically defined by the deposition nozzle size. If the resolution limitation is not considered when designing for Large-Scale Additive Manufacturing ...
