Viscoelastic damper is a simple and efficient passive energy dissipation device, which is composed of viscoelastic materials clamped with constrained steel plates. It can improve the structural damping and mitigate the seismic or wind-induced vibration response of building structures through the shearing hysteric deformation energy dissipation of viscoelastic materials. To study the energy dissipation and hysteresis characteristics of viscoelastic dampers, two rubber viscoelastic dampers were designed and manufactured and tested for deformation correlation and frequency correlation cyclic loading. The mechanical properties such as energy consumption per cycle, maximum damping force, storage shear modulus, equivalent damping ratio and their changing rules under different working conditions were analyzed. Results show that the hysteretic curve of rubber viscoelastic damper is plump and stable, and its energy dissipation capacity is remarkable. With the increase of deformation, the area of hysteresis loops increases. The mechanical properties have obvious correlation with deformation amplitude, but little with loading frequency. According to the highly non-linear characteristics of the hysteretic curves, a mechanical model considering various non-linear factors is proposed to simulate the hysteretic performance of this kind of viscoelastic damper. The simulated results are in good agreement with the experimental ones and the deviations of each mechanical property are less than 9.72%. The validity of this theoretical model and the rationality of its application to nonlinear time history analysis are verified. [ABSTRACT FROM AUTHOR]

To improve the development of life-cycle multihazard-based design theory for high-performance structures in China, the research progress of this field was summarized and the research framework was systematically set up. The researches on the probabilistic occurrence models of individual hazard and multiple hazards were elaborated. The analytical models concerning the environmental effects on the time-variant deterioration of materials and structural component were summarized by taking the carbonization corrosion and wind induced fatigue as examples, which were conducive to guide the life-cycle performance assessment of high-performance structures subjected to multiple hazards. Moreover, the research status of the fragility analysis and the life-cycle cost based optimization design approach for high-performance structures were discussed in detail. The combined effects of multiple hazards and the lifetime deterioration of structural performance, which are neglected in the traditional specifications, can be rationally included in the life-cycle multihazard-based structural analysis and design methodology, which is of great significance for the development of building structural design.

A precast insulation reinforced concrete shear wall with diagonal bracing is studied. Four triangular hollow areas are reserved inside the wall, in which the insulation boards are filled. The inclined steel bars are set along the diagonal direction in the wall. The low cyclic reversed loading experiments were carried out on three diagonal bracing insulation shear walls with three different shear span ratios of 1.0, 1. 5 , 2.0 respectively. Systematic analyses were made on failure modes, hysteretic curves, skeleton curves, bearing capacity, deformation capacity, stiffness degradation and energy dissipation capacity of the different specimens. The same experiment on an ordinary shear wall with shear span ratio of 1.5 was carried out to make a comparative analysis of the seismic behavior. At last, numerical simulations of these specimens were made by finite element analysis software ABAQUS. The results show that with the same shear span ratio, the bearing capacity of the insulation shear walls with diagonal bracing is slightly lower than that of the ordinary shear wall. However, the development of cracks is delayed. The ductility is improved and the energy dissipation capacity of the wall is increased significantly, which is helpful to resist earthquake action. As for insulation walls with diagonal bracing, with the increase of shear span ratio, the bearing capacity decreases, whereas the deformation ability increases. The stiffness degradation delays and energy dissipation capacity increases. Moreover, it has been proved that FE model can well simulate the seismic behavior of the specimens by the comparisons with experiment results. [ABSTRACT FROM AUTHOR]

Based on static and dynamic cyclic loading tests on 16 reinforced concrete (R C) column specimens，the influence of dynamic effect on the seismic performance of RC columns was investigated. Static and dynamic damage indexes were established on the basis of the modified Park-Ang damage index，which take into account the influences of both the maximum displacement and the number of loading cycles on the damage and deterioration behavior of RC columns. The relationships between the degradation coefficients and the corresponding displacement ratio or damage index were established for the static and dynamic loading conditions. With the combination of the constructed dynamic degradation functions, a hysteretic model for RC columns that can reflect the negative stiffness stage, cyclic deterioration of strength and stiffness and pinching effect was developed. The effectiveness of the proposed model was verified by comparing with the hysteretic curves of RC columns obtained from the static and dynamic loading tests. It is found that the dynamic hysteretic model performs better than the static hysteretic model in representing the mechanical behaviors of RC columns under seismic loading rate. The hysteretic model and the proposed method can provide a valuable reference for reasonable seismic analyses of RC structures. [ABSTRACT FROM AUTHOR]

Due to large information of multi-DOF structures, there are obvious deficiencies when using decentralized control strategy comparing with using the centralized control strategy. The market-based control (MBC) theory is decentralized control strategy based on the non-classic information only requires the information of discrete floors. As a nonlinear analysis method for engineering structures，the force analogy method (FAM) has the advantages of fast computation speed, small storage space and so on. Combining the FAM with the multi-MBC (MMBC) control strategy can greatly improve the efficiency of nonlinear analysis processes. The nonlinear MMBC decentralized controller design method based on the FAM was proposed, and the logarithmic supply and demand function model was built. The numerical analysis shows that the presented nonlinear MBC controller can achieve good control effect. In addition，the nonlinear MBC control strategy has strong adaptability even when the control device fails and it can achieve optimal real-time control through price mechanism, meanwhile its robustness is strong.

The seismic performance of reinforced concrete (RC) structure under earthquake is obviously affected by the strain rate effect under high rate loading. Therefore, the strain rate effect should be considered when carrying out seismic performance analysis and design for RC structures. A large number of experiments on RC specimens under various rates of loading were collected and analyzed, and the specimens were used to develop the equivalent mechanical model. The material performance changing rule and trend of RC structure element subjected to various loading rate were investigated such that a database including numerous of test results of RC structural members under dynamic loads with different loading rate was established. The database' s interface is friendly and the retrieval system is efficient. Commonly used structural members, such as beams, columns, joints and shear walls, are included in the established database. [ABSTRACT FROM AUTHOR]

To eliminate the influence of concrete discreteness, quasi-static test of the same reinforced concrete (RC) column under different loading rates was carried out by the electro-hydraulic servo test system. The displacement-controlled loading, with loading rates of 0.2mm/s and 40mm/s, respectively, was adopted. The test results show that the mechanical properties of the specimen, such as the bearing capacity, stiffness degradation, bearing capacity degradation and cumulative energy dissipation, are directly related to the loading rate. The bearing capacity and cumulative energy dissipation of the specimens are improved under the loading rate of 40mm/s. With the increase of the loading amplitude, the influence of loading rate gradually decreases. Stiffness degradation and bearing capacity degradation of the specimens are more significant under rapid loading. With the increase of loading rate, the softening stage is shortened with more obvious damage process. Besides, the ductility of the specimen and the deformation capacity are decreased. The coupling interaction of bidirectional loading accelerates the failure process of the specimens. The cracking of the concrete, the buckling of the reinforcement bar, the spalling of the concrete and the yielding of the longitudinal reinforcement bar occur in the range of lower displacement level. With the increase of loading rate, the coupling interaction of bidirectional loading is further strengthened, and the deformation capacity of the specimen is obviously reduced.

Given that dynamic effects have rarely been considered in current hysteretic model for RC walls, a new hysteretic model for RC walls considering strain rate effect was proposed based on the quasi-static and dynamic loading tests of nine RC shear walls, meanwhile the corresponding MATLAB program was developed. This program was employed to simulate the hysteretic behavior of the mentioned nine specimens and six other specimens under quasistatic and dynamic loading tests. Results show that the proposed restoring force model can describe the dynamic properties of RC walls with a good accuracy in the range of seismic strain rate. Moreover, the proposed model was used to simulate the earthquake response of a single-span six-story RC structure with and without considering strain rate. Results show that ductility reduces and brittle failure occurs earlier when considering strain rate effect. Thus, the strain rate effect should be considered properly in structural elasto-plastic seismic analysis. [ABSTRACT FROM AUTHOR]
