Special Issue Information

Dear Colleagues,

The Special Issue is devoted to presenting the most recent research in the field of seismic design and analysis. In particular, its aim is to collect papers regarding both the assessment of original state-of-the-art and the new design and analysis methods available for structures in seismic areas. The papers can include laboratory and field tests or methods of computation and field observation of structural behaviour. It is well known that due to the aging of concrete or to the non-seismic code adopted in the design phase, there are a lot of structures that need to be retrofitted in order to increase their ability to resist to seismic actions. On the other hand, for new buildings there is the necessity to design structures that can resist high horizontal forces without a significant increase in structural cost.

In this Special Issue, the guest editors will ask for high-quality original research articles focused both on the state-of-the-art and on the new developing techniques for seismic protection. We could promote the Special Issue by means of our institutional web page, by informing all the Italian community of structural engineering professors and all the other foreign colleagues that are involved in several research projects with the editors.

The seismic capacity of the main Uto City Hall building, which was severely damaged by the 2016 Kumamoto Earthquake, was evaluated by the proposed pushover-based procedure. In this procedure, the seismic capacity index of the building is defined as the maximum scaling factor of the seismic input, for which the local responses do not exceed their limit values. From the pushover analysis result, the displacement limit of the equivalent single-degree-of-freedom model was determined. Then, the seismic capacity index was evaluated using an equivalent linearization technique. The evaluated index was re-evaluated by considering the bidirectional excitation. The pushover analysis result revealed that the torsional response is significant in the nonlinear behavior of this building. The evaluated seismic capacity implied that some structural damages, including the yielding of the beam-column joint, may have occurred during the first earthquake on 14 April 2016. Full article

An innovative, simplified, and accurate model is proposed and developed to enable simplified yet realistic time history analysis of multi-storey buildings with moment resisting connections using friction energy dissipaters in the commonly used structural analysis and design program, SAP2000. The analyses are rapid to undertake, thereby enabling detailed study of the influence of many building system effects on the overall response. This paper presents the outcome of dynamic analysis of a complete 13-storey moment resisting steel building with Sliding Hinge Joints as the beam-column connections, considering the influential self-centring factors such as MRF and gravity columns continuity as well as column base and diaphragm flexibilities. The building is one of the Te-Puni towers, which are structural steel apartment buildings with steel-concrete composite floors, designed according to the low damage design philosophy, built in Wellington, New Zealand in 2008 and which have already been subjected to two significant earthquakes. The key objectives of the research have been to take the design of the 13-storey building and convert that into the proposed simplified model required for time history seismic analysis, to undertake analysis under scaled El-Centro earthquake record, investigate the peak inter-storey drift and the residual drift of the building, and determine the influence of column base rotational stiffness, floor slab out of horizontal plane displacement, type of friction damper, and MRF and gravity column continuity. It is concluded that the response of the building is stable and predictable, as expected, and that the post-earthquake state of the building, particularly from the self-centring point of view, is well within the limits for maintaining operational continuity following an ULS level design earthquake.

Structural strength and stiffness were previously investigated to sufficiently improve the lateral load resistance against major events. Many buildings require appropriate design to effectively withstand the lateral seismic loads and reduce the corresponding damages. Design methodologies and structural elements were recently introduced to improve the energy dissipation capability and limit the high force demands under seismic loadings. The new systems are designed to protect the structural integrity and concentrate the inelasticity in a specific area, while the remaining parts are kept undamaged and intact. This study introduces a new structural system with dampers having strategic cutouts, leaving butterfly-shaped shear dampers for dominating the yielding mechanism over other brittle limit states. The new system is designed for re-establishing the conventional eccentrically braced frame system with simple linking beams. The system with strategic cutouts is subsequently used and compared with the eccentrically braced frames (EBF) system for seismic performance investigation and incremental dynamic analysis (IDA), using the OpenSees program, which is used to indicate the collapse behavior under forty-four selected ground motions. Results show that the butterfly-shaped multi-story buildings, compared to the corresponding conventional systems, are capable of enhancing the system resistance against lateral seismic loads by postponing the collapse state to the larger drift ratio values.

Title: Prediction of the maximum seismic member force in a superstructure of a base-isolated frame building by using pushover analysis

Keywords; base-isolated building, pushover analysis, higher-mode effect, modal decomposition, member force

It is essential for the seismic design of a base-isolated building that the seismic response of the superstructure remains within the elastic range. For this purpose, the evaluation of the maximum seismic member force in a superstructure is an important issue. In this article, the maximum seismic member force of five- and fourteen-story reinforced concrete base-isolated frame buildings are predicted by using pushover analysis. In the first stage of this study, the nonlinear dynamic (time-history) analysis of those base-isolated frame buildings were carried out, and the nonlinear modal responses of the first and second modes were calculated based on pushover analysis results. In the second stage of this study, a set of pushover analysis is proposed considering the combination of the first and second modal responses, and the predicted maximum member forces were compared to the nonlinear dynamic analysis results. The results show that the predicted maximum member forces by the proposed set of pushover analyses were satisfactorily accurate, while the predicted results considering only the first mode were significantly inaccurate.
