Cui Jie,Dang Yaoguo,Liu Sifeng,Xie Naiming

Strategic Study of CAE 2010, Volume 12, Issue 2,   Pages 108-112

Abstract:

According to the theory of prior using of new information,based on the research of already existed strengthening buffer operators, some new strengthening buffer operators are established. Meanwhile,their characters are studied. The flaw that the existing strengthening buffer operators can,t fully use new information of the data sequence is overcame. The problem that there are some contradictions between quantitative analysis and qualitative analysis in pretreatment for vibration data sequences is resolved effectively. An example simulation shows, compared with the existing strengthening buffer operators, the kind of new strengthening buffer operators increases the forecast precision of GM(1,1) remarkably.

Controlling interstory drift ratio profiles via topology optimization strategies

Frontiers of Structural and Civil Engineering 2023, Volume 17, Issue 2,   Pages 165-178 doi: 10.1007/s11709-022-0892-3

Abstract: An approach to control the profiles of interstory drift ratios along the height of building structures via topology optimization is proposed herein. The theoretical foundation of the proposed approach involves solving a min–max optimization problem to suppress the maximum interstory drift ratio among all stories. Two formulations are suggested: one inherits the bound formulation and the other utilizes a p-norm function to aggregate all individual interstory drift ratios. The proposed methodology can shape the interstory drift ratio profiles into inverted triangular or quadratic patterns because it realizes profile control using a group of shape weight coefficients. The proposed formulations are validated via a series of numerical examples. The disparity between the two formulations is clear. The optimization results show the optimal structural features for controlling the interstory drift ratios under different requirements.

Autogenous healing mechanism of cement-based materials

Frontiers of Structural and Civil Engineering   Pages 948-963 doi: 10.1007/s11709-023-0960-3

Abstract: Autogenous self-healing is the innate and fundamental repair capability of cement-based materials for healing cracks. Many researchers have investigated factors that influence autogenous healing. However, systematic research on the autogenous healing mechanism of cement-based materials is lacking. The healing process mainly involves a chemical process, including further hydration of unhydrated cement and carbonation of calcium oxide and calcium hydroxide. Hence, the autogenous healing process is influenced by the material constituents of the cement composite and the ambient environment. In this study, different factors influencing the healing process of cement-based materials were investigated. Scanning electron microscopy and optical microscopy were used to examine the autogenous healing mechanism, and the maximum healing capacity was assessed. Furthermore, detailed theoretical analysis and quantitative detection of autogenous healing were conducted. This study provides a valuable reference for developing an improved healing technique for cement-based composites.

Topology optimization of transient problem with maximum dynamic response constraint using SOAR scheme

Frontiers of Mechanical Engineering 2021, Volume 16, Issue 3,   Pages 593-606 doi: 10.1007/s11465-021-0636-4

Abstract: This paper proposes a novel method for the continuum topology optimization of transient vibration problem with maximum dynamic response constraint. An aggregated index in the form of an integral function is presented to cope with the maximum response constraint in the time domain. The density filter solid isotropic material with penalization method combined with threshold projection is developed. The sensitivities of the proposed index with respect to design variables are conducted. To reduce computational cost, the second-order Arnoldi reduction (SOAR) scheme is employed in transient analysis. Influences of aggregate parameter, duration of loading period, interval time, and number of basis vectors in the SOAR scheme on the final designs are discussed through typical examples while unambiguous configuration can be achieved. Through comparison with the corresponding static response from the final designs, the optimized results clearly demonstrate that the transient effects cannot be ignored in structural topology optimization.
