Papers by Farzad Hatami
If this document is being applied in relation to a particular asset then this should be reflected in the relevant appointments.
This document is applicable to assets of all sizes and all levels of complexity. This includes portfolios of buildings, campuses, infrastructure networks, individual buildings and pieces of infrastructure such as roads, bridges, footpaths, streetlights, water pipes or sewers. The requirements in this document should be applied in a way that is proportionate and appropriate to the scale and complexity of the asset.
Continuity of information management over the lifetime of an asset is important and it is recommended that all feasible steps (including transfer of the asset information model) are taken to ensure this whenever an asset is transferred from one owner to another.
DOI 10.1088/1361-665X/acbcb0
To solve this problem, this paper proposes a new dual system. The proposed dual system includes a moment resting frame and a frame with a replaceable beam with a smaller cross-section than that of the main beam which is placed at the mid-span of the beam and designed to act as a shear fuse. This shifts the location of the plastic hinge from the ends of the beam to its middle since the shear fuse yields in shear prior to the flexural yielding of the main beam. This dual system eliminates the need to comply with the rigorous limitation on the beam clear span to the depth ratio that is proposed by seismic design codes. Moreover, this system enjoys an increase in the amount of stiffness. It is worth mentioning that this dual system increases the resilience of the building as the shear fuse is readily replaceable after an earthquake.
With the verification of an experimental model, finite element numerical models are produced. The ABAQUS numerical models show that system that includes both moments resisting frame and shear link frame functions much better than the moment-resisting frames system. As a result, by enjoying this dual system, as well as using the ductility of moment-resisting frames, the stiffness of the building does not decrease noticeably.
Keywords: Moment resisting frame, Dual System, Shear Link, Low span to depth ratio.

In this study, nine samples of bridge piers are reinforced by two types of SMA (NiTi and Cu-Al-Mn) in plastic hinge regions where highperformance fiber-reinforced concrete (HPFRC) is additionally used to enhance the ductility of piers. Shape memory alloys (SMAs), with their unique ability to undergo large deformations and recover to their initial shapes through the removal of stress without significant residual strain, have become attractive materials in bridge engineering. To investigate the effects of SMAs and HPFRC on seismic performance of concrete bridge piers, 28 near-field ground-motion record pairs are selected. Then, the models are analyzed using the incremental dynamic analysis (IDA) method and fragility curves are derived. The results show that using SMAs leads to the reduction of residual drift. Also, using HPFRC increases the capacity of the models. Furthermore, the model with HPFRC and NiTi shows the best performance in terms of capacity and residual drift reduction.
It was a great pleasure to work with Professor Mesbah Saybani and Eng. Amirmozafar Benshams.
