Abstract ：
桥梁颤振敏感性表征设计参数对颤振临界风速的影响，是探究桥梁颤振机理与提升颤振性能的重要工具。为帮助设计人员在设计阶段高效精准地获取结构动力特性及颤振导数对大跨度桥梁颤振性能的影响规律，提出一种基于直接微分法的桥梁三维颤振敏感性分析方法。该方法基于系统矩阵的左右特征向量正交特性，构建在设计参数小幅摄动时桥梁多模态耦合颤振规格化条件，结合颤振临界条件得到系统特征值及颤振临界风速对设计参数的敏感性。为检验该方法，以理想薄平板断面简支梁桥为算例，与有限差分方法进行比较，表明该方法具有较高的精度和计算效率。将该方法用于一座大跨度悬索桥的颤振敏感性分析，结果表明：对于采用闭口流线型主梁断面的大跨度桥梁，一阶对称竖弯和一阶对称扭转模态对桥梁颤振影响最大；增大桥梁结构的阻尼比、模态质量及基础扭弯频率比，均会提升桥梁颤振临界风速；颤振导数中，A~*_2影响最显著，A~*_3、A~*_1和H~*_3的影响次之，其它颤振导数的影响则基本可以忽略。

Abstract ：
In order to determine the difference and similarity of along-wind loads of high-rise buildings between Chinese Taiwan and Chinese mainland areas，benchmarking analysis was used to compare the wind load code for buildings on both sides of the Taiwan strait，and multi-factor analysis of along-wind loads of high-rise buildings was conducted using the uniform design method. The results show that there are significant differences in the basic wind speed sample method and extreme distribution parameter estimation methods. The wind pressure height coefficient distribution and conversion coefficient of design wind speed in different return periods for the two standards are roughly the same；The turbulence intensity values of the Taiwan code is significantly larger than that of the mainland code；For the wind pressure calculation of main wind-force resisting system and cladding， Taiwan wind load code adopts classification method，while the Mainland wind load code adopts a unified expression. There are significant differences between the two standards in the combination of design wind loads of along-wind，cross-wind，and torsional directions. Taking the base shear and base bending moment as evaluation indexes，the influence of aspect ratio H BL，exposure factor α，gust effect factor Cg，wind load shape coefficient Cp ，and turbulence intensity Iz on the along-wind loads of high-rise buildings gradually decreases，and the aspect ratio and exposure factor are the main influencing factors. The influence of gust effect factor on along-wind load increases with the increase of the aspect ratio of the structure，and when the aspect ratio increases to a certain value，it becomes the main factor that dominates the along-wind loads of the both sides. © 2023 Science Press.

为明确海峡两岸高层建筑顺风向风荷载的异同,对两岸建筑风荷载标准进行了对标分析,并采用均匀设计方法进行了高层建筑顺风向风荷载多因素分析。研究表明:两岸风荷载标准中基本风速取样方法和极值分布参数取值方法存在明显区别,风压高度变化系数分布和不同重现期的设计风速转换系数大致相同,台湾标准给出的湍流强度建议值明显大于大陆标准;台湾标准分类计算建筑物主体和围护结构的设计风压,大陆标准采用统一表达式,两者给出的设计风荷载组合方式区别明显;以基底剪力和基底弯矩作为评价指标,H/(BL)(1/2)(高宽比)、α地面粗糙度指数)、C_g(脉动效应系数)、C_p(风荷载体型系数)和I_z(湍流强度),对高层建筑顺风向风荷载的影响程度依次减小,H/(BL)(1/2)和α为主要影响因素;随H/(BL)(1/2)的增大,C_g对顺风向风荷载的影响逐渐增强,当H/(BL)(1/2)增大到一定程度时,C_g成为主导因素。

Abstract ：
为明确闽台地区平均风速剖面的合理取值,本文以"平均风速剖面特征参数是确定结构风荷载极值的基础性参数"为前提,提出了一种平均风速剖面预测的新方法:风荷载极值等效法。以福建沿海8个测风塔的实测风速数据和某高层建筑为例,利用不同极值分布模型及参数估计方法,对闽台沿海地区展开了平均风速剖面预测研究,并将预测结果与两岸现行规范建议值和统计均值等进行了比较。结果表明:(1)与D-H模型相比,指数律模型与对数律模型更适合闽台沿海地区平均风速剖面预测,建议使用指数律模型;(2)采用本文方法预测得到的平均风速剖面特征参数大于现行规范,同时也大于统计均值,表明目前平均风速剖面取值可能偏于危险。

Abstract ：
To clarify the safety performance of downward movable scaffolding systems (MSSs) in strong wind environment, this paper takes a downward mobile scaffolding system with span of 50 m (MSS50) in the southeast coastal area as the research object to systematically investigate its flutter, vortex, and buffeting performance by aero⁃elastic model wind tunnel test and numerical calculation. Results show that vertical displacement and torsion angle were critical factors of MSS in fixing and moving conditions respectively. In the fixing condition, MSS50 could meet the operation requirements of 8⁃level strong wind (20. 7 m/ s) and resist 14⁃level wind (46. 1 m/ s) . In the moving condition, the main structure could meet the operation requirements of 8⁃level strong wind in the case of proper measures. The multi⁃modal coupling frequency domain buffeting calculation method and the equivalent static gust wind load method in Wind⁃resistant Design Specification for Highway Bridges could be used to calculate the buffeting response of MSS with acceptable accuracy. The multi⁃modal coupling frequency domain buffeting calculation method has higher accuracy than the equivalent static gust wind load method and is recommended to calculate the buffeting response of MSS. © 2022 Harbin Institute of Technology.

为明确强风环境中下行式移动模架的抗风安全性,以东南沿海某50 m跨下行式移动模架为研究对象,采用气弹模型风洞试验和数值计算相结合的方式,对其颤振、涡振和抖振性能进行了较系统的研究.结果表明:结构竖向位移和扭转角分别是移动模架合模和开模工况时的控制性因素;合模工况时,移动模架主体结构能够满足8级强风(20.7 m/s)的作业要求,且能够抵抗14级风(46.1 m/s)作用;开模工况时,在措施得当的情况下主体结构能够满足8级强风的作业要求;多模态耦合频域抖振计算法和《公路桥梁抗风设计规范》中的等效静阵风荷载法均可以用于移动模架的抖振响应计算,且具有一定的精度,推荐采用精度较高的多模态耦合频域抖振计算法.

Abstract ：
A reciprocating low-cycle pseudo-static loading test on three reinforced concrete (RC) piles was performed in the Structural Laboratory of Fuzhou University to study their failure modes and seismic behaviors. The modified calculations of lateral deformation and soil pressure along the piles were further verified based on the test results. In this article, a displacement-based simplified calculation for pile-soil interaction of piles was proposed based on the shear equilibrium and test results, and then it was compared with the traditional m method and p-y curve method. The test results show that m method overestimated the bearing capacity of piles, leading to a lower safety factor for the piles. Therefore, it was not suitable to calculate the internal force and lateral displacement under large displacement. Moreover, the ductility of prestress high-strength concrete pipe piles or RC piles would be overestimated by the p-y curve method. Although the p-y curve method took into account the nonlinearity of soil, the calculated force-lateral displacement curve still showed a significant difference with the test results under large deformation. The test results further show that the modified calculation of lateral displacement and soil pressure can be preferably validated by test results, which indicates that the displacement law of laterally loaded pile can be accurately assessed. Furthermore, the proposed displacement-based simplified calculation showed a good agreement with the test values in terms of internal forces and force-lateral displacement curve. Therefore, it was recommended for analyzing the cyclic behavior of laterally loaded pile foundations considering soil-pile interaction in integral abutments jointless bridges (IAJBs).
