Spectra in Acceleration-Displacement format

Figure  4。  (a)  Longitudinal;  (b)  transverse  component  of  Herceg  Novi  records,  PGA   1g;

(c) acceleration response spectra (5%  damping)  of  X  and  Y  components  and  Ordinance soil c spectrum; and (d) spectra in AD   format。

displacement required for each investigated PGA level are summarized in Table III, which shows that the ‘as-built’ structure is able to satisfy the LSSD in each direction for 0。20g PGA level even if, especially in both positive and negative X directions, the capacity slightly exceeds the demand。 Moreover, increasing the seismic action up to a PGA of 0。30g, such verification is satisfied only in direction PY ; at this PGA level, the maximum gap in terms of maximum top displacement is provided in direction NX where the difference between seismic demand and displacement capacity is 0。0301 m (0。0927 m vs 0。0626 m) corresponding to a performance gap of 48%。 RP对不满足设计的RC结构的抗震加固英文文献和中文翻译(7):http://www.youerw.com/fanyi/lunwen_82095.html
