The structural "firsts" of the Seagram Building included: first tall building to combine a
braced frame with a moment frame (moment frames help resist wind and seismic forces), first to use a vertical truss bracing system, first to use high-strength bolted connections, and first to use a composite structural steel and concrete shear walls.

braced frame seismic behavior.

braced frame structure," World Earthquake Engineering, vol.
Among proposed lateral loading system, eccentrically
braced frame, though has little stiffness compared to the types of convergent braces, it has high strength, especially high energy absorption capability and tolerates stability hysteresis cycle under reciprocating loadings that achieving to this important issue is not possible regarding convergent braces due to buckling under the pressure.
A
braced frame is an efficient structural form for resisting lateral loads.
The tower's
braced frame system also provides superior seismic performance in compliance with California's strict criteria for acute care facilities.
Their topics include predicting the seismic displacement of landslides and gravity walls using a multi-block model, dynamic responses of high-speed railway bridges under earthquakes and their influences on running safety, seismic resistant
braced frame structures with shape-memory alloy-based self- centering damping devices, applying numerical tools for modelling granular soil behavior under earthquakes, applying dissipated energy to model cyclic loaded saturated soils, and simplified modal response history analysis for asymmetric-plan structures.
Depending on the style of climbing wall, the framework's fabrication and assembly begins with cutting hundreds of pieces of angle iron, measuring from 3" x 3" x 1/4" thick to 5" x 5" x 1/2" thick, and welding these pieces together to form 20' - 40' reinforced and
braced frame sections.
There's a
braced frame to cope with the claimed 148bhp and a slimmer fuel tank with a shorter reach to the bars; it feels more compact and remains one of the best out-of- the crate track bikes available.
It is calculated from [C.sub.mx] = 0.6-0.4(M1/M2) for the
braced frame member without transverse loading between the ends and [C.sub.mx] = 1 + [psi] ([f.sub.a]/[F'.sub.e]) for the
braced frame member with transverse loading.
Steel
braced frame systems are efficient since frame members work together like a truss and resist primarily axial loads with little or no bending in the members until the compression braces buckle.
