Prestressed shell structures
Using strong but lightweight materials for shell structures is beneficial in terms of loads that has to be supported by the substructure. In general shell structures for architecture gets its shape by the self-weight acting on the structure, however when lightweight materials are used the self-weight might not be large enough to be the governing design load case. By adding prestress to the shell structure the lack of sufficient self-weight can be dealt with.
Long-span tensile timber roof structures
Applying the stress ribbon concept the possibilities of using timber in pure tension in order to span large distances is investigated. Currently I supervise two master’s thesis students. We are looking into design and analysis methods, applicable load cases and develop construction concepts. Previously I supervised a master’s thesis project focusing on the general ideas of the concept, preliminary design and environmental benefits compared to conventional construction methods for large span halls.
