ANSI S2.32-1982 机械灵活性的实验测定方法:第2部分:用单点变换激发方法进行测量

The scope of this standard includes measurement of mobility, accelerance, or dynamic compliance, either as a driving point measurement, or as a transfer measurement. It also applies to the determination of the arithmetic reciprocals of those ratios as fr

ANSI/ASA S2.32-1982 机械导纳的试验测定方法,第2部分:应用单点平移激发法测量

The scope of this standard includes measurement of mobility, accelerance, or dynamic compliance, either as a driving point measurement, or as a transfer measurement. It also applies to the determination of the arithmetic reciprocals of those ratios as free effective mass. Although excitation is applied at a single point, there is no limit on the number of points at which simultaneous measurements of the motion response may be made. Multiple response measurements are required, for example, for modal analyses.

prEN 1998-3 欧洲规范 8 抗震结构设计 第3部分：建筑物和桥梁的评估和改造

EN 1998-3 is intended to provide criteria for the assessment of the seismic performance of existing individual buildings or bridges, to describe the procedure to be followed in selecting necessary corrective measures and to set forth criteria for the design of retrofitting measures. It covers the seismic assessment and retrofitting of buildings and bridges made of the more commonly used structural materials: concrete, steel and composite, timber and masonry. Although the provisions of EN 1998-3 are applicable to all common categories of buildings and bridges, the seismic assessment and retrofitting of monuments and historical structures often requires different types of provisions and approaches, depending on the nature of the monuments. It is also not intended for the vulnerability assessment of populations or groups of structures in the scope of seismic risk evaluation.

prEN 1998-2 欧洲规范 8 抗震结构设计 第2部分：桥梁

EN 1998-2 is intended to be applied to the design of new bridges in seismic regions. It covers the design of reinforced concrete, steel and composite steel-concrete bridges and provides guidance for the design of timber bridges. EN 1998-2 is applicable to the seismic design of bridges exploiting ductility in structural members or through the use of antiseismic devices. When ductility is exploited, this part primarily covers bridges in which the horizontal seismic actions are mainly resisted through bending of the piers or at the abutments; i.e. of bridges composed of vertical or nearly vertical pier systems supporting the traffic deck superstructure. It is also applicable to the seismic design of arched bridges, although its provisions should not be considered as fully covering these cases. Suspension bridges and masonry bridges, moveable bridges and floating bridges are not included in the scope of EN 1998-2.
