Special Issue Information

Dear Colleagues,

Due to their good mechanical properties, simplicity of design, rationality and easy availability, concrete structures are widely used in the construction of many buildings. Since the application of concrete structures is very wide, new and innovative methods of concrete preparation, as well as new ways of applying concrete in structural systems, are developing every day. In addition, new approaches to the design, calculation and optimization of structures are being developed.

In seismic engineering, inelastic response, ductility and safety against failure are the most important performance requirements for concrete structures. Furthermore, the development and use of different types of seismic insulation devices and shock absorbers play an important role in improving the seismic resistance of concrete structures. To simplify the nonlinear seismic analysis of reinforced concrete structures, the development of new methods for calculation and modelling is crucial. Experimental techniques are a significant and unavoidable part of advanced engineering design and calculation methods, especially in the verification of new calculation methods and new constructive systems.

Therefore, this Special Issue intends to present new ideas in the calculation and modelling of seismically resistant concrete structures, as well as new achievements in seismic base isolation and experimental results in the seismic performance of concrete structures.

Topics of interest include but are not limited to:

  • Optimization of reinforced concrete structures;
  • Seismic performance of concrete structures;
  • Seismic performance of high-strength concrete structures;
  • Design and modelling of concrete structures;
  • Experimental research of concrete structures;
  • Experimental tests through building procedures;
  • Application of devices for seismic insulation on concrete structures;
  • Application of shock absorbers in concrete structures;
  • Damage assessment of concrete structures through experimental and numerical estimation of dynamic characteristics;
  • Seismic retrofit, strengthening and rehabilitation of concrete structures.

Fiber-based finite element analysis (FB-FEA) has been widely recognized for its ability to reproduce experimental results and is also a reliable method for evaluating the nonlinear seismic response of pile-supported wharves (PSWs). Design practice often employs frame analysis (FA) due to its easy implementation. To precisely reproduce the nonlinear seismic response of PSW using FA, it is necessary to configure mechanical properties such as the hinge property correctly. However, it is unclear whether the hinge properties proposed in previous studies can be applied to PSWs with spun piles. In this study, a novel FA method was developed to investigate the nonlinear seismic response of PSWs with corroded spun piles considering PC bar area reduction, deteriorated material properties, the bending stiffness reduction factor, and the moment–curvature relationship of the spun pile. The nonlinear seismic response of corroded PSWs was determined by performing pushover analysis using three methods: FA using the method of the previous study (FA-1), the proposed FA method (FA-2), and FB-FEA. As regards PSW foundations, vertical pile and batter pile configurations were considered. The pushover analysis results were compared in terms of several parameters, such as the natural period, plastic hinge formation, and load capacity of the corroded PSWs. The FA-2 results agreed very well with the FB-FEA results, while the FA-1 results were less precise with respect to the natural periods and load capacities of corroded PSWs. The results indicated that the bending stiffness reduction factor, moment–curvature relationship, and axial load–bending moment (P–M) capacity of the corroded spun piles should be appropriately defined. Corrosion had greater negative impacts on the compressive axial load and bending moment capacities of the spun pile than on its tensile axial load capacity. Full article

As special equipment for storing energy, the safety performance of liquified natural gas (LNG) storage tanks under earthquake action is extremely important. To study the dynamic characteristics of the large-scale LNG storage tank structure and the dynamic response under earthquake action, the shaking table test and numerical simulation analysis of the LNG storage tank structure model are carried out. The results of the shaking table test demonstrate that the natural vibration frequency of the tank model is significantly reduced after the isolation measures are taken. The acceleration response of the seismic storage tank increases approximately linearly along the direction of height, and the seismic isolation bearing has a significant seismic isolation effect on the acceleration of the storage tank. The numerical simulation results show that the seismic responses and their spectral characteristic curves of the numerical model and the shaking table test are the same, which verifies the feasibility and rationality of the numerical model. After seismic isolation measures are taken, the seismic responses of large-scale LNG storage tanks, such as base shear force, overturning bending moment and acceleration, are reduced to varying degrees, but the displacement of the storage tank increases to some extent. When carrying out the seismic isolation design of LNG storage tanks, it is necessary to focus on the displacement of the storage tank to prevent damage of the auxiliary pipeline led by excessive displacement.
