Evaluation and Repair of Steel Structure Damaged by Fire
In recent years, steel structures have been widely used in buildings because of their advantages in self-weight and seismic performance. However, due to the great influence of temperature on steel structure, o...

Life-cycle failure probability analysis of deteriorated RC bridges under multiple hazards of earthquakes and strong winds
Engineering structures may be exposed to one or more extreme hazards during their life-cycles. Current structural design specifications usually treat multiple hazards separately in designing structures and the...

Seismic response of large-span spatial structures under multi-support and multidimensional excitations including rotational components
To achieve rational and precise seismic response predictions of large span spatial structures (LSSSs), the inherent non-uniformity and multidimensionality characteristics of earthquake ground motions should be...

Simulation of multi-support depth-varying earthquake ground motions within heterogeneous onshore and offshore sites
This paper presents a novel approach to model and simulate the multi-support depth-varying seismic motions (MDSMs) within heterogeneous offshore and onshore sites. Based on 1D wave propagation theory, the thre...

Rapid repair techniques for severely earthquake-damaged circular bridge piers with flexural failure mode
In this study, three rapid repair techniques are proposed to retrofit circular bridge piers that are severely damaged by the flexural failure mode in major earthquakes. The quasi-static tests on three 1:2.5 sc...

Market-based control strategy for long-span structures considering the multi-time delay issue
To solve the different time delays that exist in the control device installed on spatial structures, in this study, discrete analysis using a 2 N precise algorithm was selected ...

Research on the influencing factors for residual displacements of RC bridge columns subjected to earthquake loading
Following the 1995 Kobe earthquake, many RC bridge columns were demolished due to a residual drift ratio of more than 1.75 % even though they did not collapse. The residual drift ratio is a quantitative index ...

Apparent velocity estimation with P-SV ratio method
The apparent velocity of the incident wave is an important parameter for simulating rotational ground motion with theoretical methods, but it is difficult to estimate effectively when there is only a single re...

Torsionally coupled dynamic performance analysis of asymmetric offshore platforms subjected to wave and earthquake loadings
The dynamic equations of motion of asymmetric offshore platforms under three different environmental conditions: seismic action, wave action and their combination are established in this paper. In establishing...

3-D consistency dynamic constitutive model of concrete
Based on the consistency-viscoplastic constitutive model, the static William-Warnke model with threeparameters is modified and a consistency-viscoplastic William-Warnke model with three-parameters is developed...

A new framework for evaluating along-wind responses of a transmission tower
In this paper, an analytical framework to evaluate the along-wind-induced dynamic responses of a transmission tower is presented. Two analytical models and a new method are developed: (1) a higher mode general...

Studies on structural vibration control with MR dampers using μGA
A new approach to reducing the seismic response of spatial structures with magneto-rheological (MR) dampers is presented in this paper. The Genetic Algorithm with small populations (μGA) is used to optimize th...
