MacRae (7) and Ji (8) revealed that continuous columns in concentrically braced frames can reduce story drift
According to the "code for seismic design of buildings" (GB50011-2010), the limits on story drift
of steel structure under frequent and rare earthquakes are taken as 1/250 and 1/50, respectively.
LVDT1 measured the story drift
that is the basis for further analysis of the panel performance.
Figure 3 shows the final configuration of shear walls, which satisfies the lateral displacement and inter- story drift
limits for the x-direction wind.
Key words: Seismic Base Isolation Building, Non-linear Time History Analysis, Lead Rubber Bearings, Story Drift
, Time Period.
Earthquake induced envelops of maximum displacement, story drift
, story shear and overturning moment (OTM) of the building are shown in Fig.
The maximum story drift
can be reduced significantly and kept below 1% for all cases which is within acceptable limit for moderate intensity earthquake.
e story drift
to story height ratio) corresponding to the damage in the specimens are summarized in Table 3.
The residual story drift
in third quadrant nearly matched for both the frames.
Non-structural damage measures are related to story drifts
and storey accelerations.
Johnson dresses his social criticism in lively, colloquial writing, and though his story drifts
in the aftermath of the tragedy, he lands a number of palpable hits.
The story drifts
somewhere between the time of ancient Greek mythology and modern life; the characters are half-monstrous, half-human; and the format is a witty genre-crossing mix of poetry and prose.
