STRCTENG 302 Steel Quiz No 7: Load paths through connections
多项选择题
The figure below shows the failure at the collector beam flange of a welded brace to collector beam in an eccentrically braced frame in the February 22, 2011 Christchurch earthquake. Choose all the statements about this failure which are correct
选项
A.The failure shows that the collector beam material was brittle at the time of the earthquake
B.This failure occurred when the brace was in tension due to earthquake loading
C.If the brace flange below the beam flange had lined up with the stiffener above the beam flange and the welds had been sufficiently strong, this failure would not have occurred
D.Because the brace flange was wider than the collector beam flange, this failure would have occurred even if the brace flange below had lined up with the stiffener above
E.The failure was a ductile tearing failure in the beam web due to overloading

Let's carefully examine the statements and the context of the failure shown in the figure, which depicts a welded brace connected to a collector beam in an eccentrically braced frame during the Christchurch earthquake.
Option 1 (from the answer list): This failure occurred when the brace was in tension due to earthquake loading.
- Rationale: In many eccentrically braced frames, braces experience alternating tension and compression during seismic loading. The failure at the collector beam flange adjacent to a welded brace often indicates a tensile force transfer path and potential yielding or fracture in the connected members under brace tension. This makes the statement plausible as a description o......Login to view full explanation登录即可查看完整答案
