Optimal seismic upgrade timing in seaports with increasing throughput demand via real options [PDF]

, 2018
A real options (RO) formulation is proposed for decision-making on the timing to upgrade the seismic performance of existing seaports with increasing throughput demand in earthquake prone areas.

Study on the Influence of Slope Static Load on Shallow Lining Support Structure

Energy Science &Engineering, EarlyView.
On the basis of the background of the shallow‐buried main adit supported by stone lining, the mechanical model of the supporting structure is constructed, and the stability of the supporting structure is analyzed by using the methods of field investigation, theoretical analysis, and numerical simulation.

Analysis on the Time-Varying Fragility of Offshore Concrete Bridge

Complexity, 2019
For offshore bridges, the most prominent problem in the whole life cycle is that it is in an earthquake prone zone and an offshore corrosion environment at the same time.

Seismic Fragility Analysis of Vertically Irregular Steel Framed Buildings

IOP Conference Series: Materials Science and Engineering, 2020
Abstract Disaster mitigation of the country requires the data of fragility curves for various typical buildings. As the number of steel buildings in the cities is increasing, development of seismic fragility curves of steel buildings are also the need of the hour.

Feasibility of using neural networks to obtain simplified capacity curves for seismic assessment [PDF]

, 2018
The selection of a given method for the seismic vulnerability assessment of buildings is mostly dependent on the scale of the analysis. Results obtained in large-scale studies are usually less accurate than the ones obtained in small-scale studies.

Simplified Estimation of Economic Seismic Risk for Buildings [PDF]

, 2004
A seismic risk assessment is often performed on behalf of a buyer of commercial buildings in seismically active regions. One outcome of the assessment is that a probable maximum loss (PML) is computed.

Numerical Modeling of Geological Fault Reactivation Using Sequential Coupling Strategies

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The interaction between fluid flow and mechanical deformation in fault zones can lead to processes of fault reactivation, triggering potential geomechanical problems such as seismicity, well collapse, fluid migration to shallower layers, and aggravated surface subsidence.

IDA-Based Seismic Fragility Analysis of a Concrete-Filled Square Tubular Frame

Buildings
Based on the incremental dynamic analysis (IDA) method, this paper conducts seismic fragility analysis of a CFST plane frame, a CFST spatial frame under 1D (one-dimensional) ground motions, and a CFST spatial frame under 2D (two-dimensional) ground ...
