Controlling interstory drift ratio profiles via topology optimization strategies

Frontiers of Structural and Civil Engineering 2023, Volume 17, Issue 2,   Pages 165-178 doi: 10.1007/s11709-022-0892-3

Abstract: An approach to control the profiles of interstory drift ratios along the height of building structuresproposed approach involves solving a min–max optimization problem to suppress the maximum interstory driftthe bound formulation and the other utilizes a p-norm function to aggregate all individual interstory driftThe proposed methodology can shape the interstory drift ratio profiles into inverted triangular or quadraticThe optimization results show the optimal structural features for controlling the interstory drift ratios

The Research on Measurement of Drift in the Evaluation Conclusion of Single Method

Chen Guohong,Li Meijuan,Chen Yantai

Strategic Study of CAE 2004, Volume 6, Issue 3,   Pages 58-63

Abstract:

In this paper drifting nature in the evaluation conclusion of single method is investigated in order to offer the experiment basis for combination evaluation. First, real evaluation problems are divided into 3 classes and emulation experiments are carried on them separately. Then, objects to be evaluated are generated by Matlab 6.1, and are evaluated by using different methods. Third, the compatibility of the comprehensive evaluation methods is discriminated. Finally, the average of the compatible methods is adopted as reference frame in order to measure drifting degree of each method quantitatively.

Behaviour of self-centring shear walls——A state of the art review

Frontiers of Structural and Civil Engineering 2023, Volume 17, Issue 1,   Pages 53-77 doi: 10.1007/s11709-022-0850-0

Abstract: The application of unbonded post-tensioning (PT) in structural walls has led to the development of advanced self-centring (rocking) shear wall systems that has significant advantages, including accelerated construction due to the incorporation of prefabricated elements and segmental construction for different materials (e.g., concrete, masonry, and timber), reduced residual drifts, and little damage upon extreme seismic and wind loads. Concrete, masonry, and timber are often used for the construction of unbonded PT structural wall systems. Despite extensive research since the 1980s, there are no well-established design guidelines available on the shear wall configuration with the required energy dissipation system, joint’s locations and acceptance criteria for shear sliding, confinement, seismic performance factors, PT loss, PT force range and residual drifts of shear walls subjected to lateral loads. In this research a comprehensive state-of-the-art literature review was performed on self-centring shear wall system. An extensive study was carried out to collect a database of 100 concrete, masonry, and self-centring shear wall tests from the literature. The established database was then used to review shear walls’ configurations, material, and components to benchmark requirements applicable for design purposes. The behaviour of concrete, masonry and timber shear walls were compared and critically analysed. The general behaviour, force-displacement performance of the walls, ductility, and seismic response factors, were critically reviewed and analysed for different self-centring wall systems to understand the effect of different parameters including configurations of the walls, material used for construction of the wall (concrete, masonry, timber) and axial stress ratio. The outcome of this research can be used to better understand the behaviour of self-centring wall system in order to develop design guidelines for such walls.

Seismic fragility assessment of revised MRT buildings considering typical construction changes

Rakesh DUMARU, Hugo RODRIGUES, Humberto VARUM

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 1,   Pages 241-266 doi: 10.1007/s11709-019-0560-4

Abstract: The present study investigates the vulnerability assessment of the prototype revised Mandatory Rule of Thumb (MRT) buildings initially designed and detailed for three storeys bare frame building; later modified through variable number of storeys (three, four, and five) and different arrangement of infill walls (bare frame, soft-storey, irregular infilled, and fully infilled). The application of infill walls increases the fundamental frequencies, stiffness, and maximum strength capacity, but reduces the deformation capability than the bare frame building. The vulnerability was also reduced through infill walls, where the probability of exceeding partial-collapse and collapse damage reduced by 80% and 50%, respectively. Furthermore, the increased in storeys (three to five) also increases the failure probability, such that partial-collapse and collapse for fully infilled increases by almost 55% and 80%, respectively. All obtained results and discussions concluded that the structural sections and details assigned for MRT building is not sufficient if considered as bare frame and soft-storey. And increase in number of storeys causes building highly vulnerable although the infill walls were considered.
