| dc.description.abstract | Abstract One of the complications with shell construction in any material today is the complexity of the building process, especially to construct and build the formwork and/or guide work. This often leads to unsatisfactory building time followed by increased cost. In a quest to rationalize this process, a concept based on flexible formwork has been explored for construction of freeform concrete structures. A computational framework has been developed, with functions for form finding and analysis of cables, membranes and shells. The theoretical predictions has been evaluated in a case study, with the construction of a full scale concrete pavilion. The predictions were found to be reliable and accurate with a mean deviation in formwork geometry of just 0.5 %. There were also indications that the cost of formwork for concrete shells can be reduced with as much as 32% - 66% through the use of a flexible formwork concept, compared to a traditional timber formwork. | sv |
