“…For the carbonation test, because the corrosive medium is carbon dioxide gas, it is also difficult to ensure a constant concentration of carbon dioxide, ambient humidity or temperature in the carbonation box when combined with the fatigue loading machine. An artificial climate simulation room is a good choice to realize the simultaneous test of fatigue loading and corrosion [178], but the influence of temperature change on the fatigue loading and other test equipment needs to be considered; the cost of such testing is also high. Another method that can experimentally simulate the combined effect of fatigue loading and corrosion is a multiple alternated simulation test, as mentioned in Section 3, but current related research is limited.…”

“…. Apparently, σ R is improperly replaced with s R in formula (6). It is proper, as commended by ISO 2394:1998, to give the value of the confidence level C less than 0.75 and the p k value for 0.95 without available information.…”

“…Sustainable development has attracted worldwide attention during the past two decades [1,2]. As a major contributor to the world's energy consumption and carbon emissions, sustainable buildings and construction industry have been emphasized [3][4][5][6]. While operational emissions owing to the considerable energy are generally assumed to play a key role in reducing building embodied carbon emissions [7][8][9], more recent attention has been given to sustainable buildings' components and materials [10][11][12].…”

With the increasing emphasis on sustainability, more and more environmentally friendly new materials and structures are developed, but they are difficult to be applied in engineering practice due to the lack of mature force resistance models. The design assisted by the testing method proposed by ISO2394:2015 and EN1990:2002 can solve this problem effectively. The aim of this paper was to analyze the characteristics of the method from a mathematical and statistical point of view based on the data and to suggest improvements. The resistance of each concrete member was derived by the design assisted by testing methods. The derivation results showed that the p values, the number of tests n , the coefficient of variation θ , and the coefficient of variation of resistance V R known or unknown have a large impact on the derived results. Also, the derivation by the Bayesian procedure or interval estimation methods might be negative. This indicates that the theory of the method is not rigorous and has some disadvantages.

Partially encased composite (PEC) members are novel composite members that efficiently exploit the advantages of mechanical properties of concrete and steel. However, the application of PEC members is limited to low-and mid-rise buildings. To overcome this limitation, a study was conducted to assess the seismic performance of a newly proposed steel-concrete hybrid coupled wall consisting of PEC wall piers coupled by means of steel beams. Parametric analysis was conducted to investigate the elastic coupling ratio (CR elastic ) and the way of changing CR elastic on the seismic behavior of the hybrid coupled PEC wall. The results showed that the CR elastic was the main parameter that affected the seismic performance of the wall. The way of changing CR elastic had little influence on the trend of the energy dissipation capacity and strength reservation of the wall. The failure mode and the development of plastic hinges of the wall were also not affected by the way of changing CR elastic . Both too large and too small CR elastic were detrimental to the seismic performance of the wall.To form an ideal plastic hinge development mode and experience good seismic performance, it is suggested that the reasonable range of CR elastic for the wall was 60%-70%.elastic coupling ratio, numerical simulation, partially encased composite member, seismic behavior, steel-concrete hybrid coupled wall | INTRODUCTIONPartially encased composite (PEC) members are a new type of composite structural members with high efficiency and extensive utilization of the advantages offered by concrete and steel. PEC members not only have the merits of high load capacity, good deformation capacity, excellent seismic performance, and fire resistance but also have the advantage of simplified connection details between concrete and steel members; thereby, they fully realize an industrialized mode of construction and assembly. [1][2][3][4] So far, numerous studies have been conducted on PEC beams and columns. [5][6][7][8][9][10][11][12][13] Mucedero et al. [5] reported that the pushdown curve of the structure with PEC beams showed the feature of monotonically increasing due to apparent catenary action. Piquer and Hernández-Figueirido [13] found that the PEC column had good fire resistance and economy compared with the steel column with or without protection. However, because of the limitations imposed by the rigidity of frame structures, the scope of application of existing PEC structures is limited to mid-rise and low-rise buildings in seismic regions. Therefore, in order to broaden the applications of PEC structures and meet the requirements of high-rise buildings in terms of their seismic performance, research on PEC shear walls is gradually being conducted. The preliminary results have showed that PEC shear wall has a full and stable hysteresis curve, excellent energy dissipation capacity, and good seismic performance. [14][15][16]
