As shown in both Fig. 2a, b, for the two pairs of the samples of the collapsed buildings and oriented buildings, the CRDbl of oriented buildings is more than twice as large as that of the collapsed buildings, and the amplitude of the CRVol of oriented buildings is also larger than that of collapsed buildings.
The integration of phase change materials (PCMs) for cooling applications in buildings reduces the amplitude of indoor air temperature fluctuations due to solar and internal gains, enabling passive solar, HVAC system downsizing or off-peak cooling designs.
The vortices formed around the structure increase the amplitude of building oscillations.
The predicted dynamic responses of the building using the actual amplitude-dependent damping characteristics were compared to those computed with constant damping parameters assumed by the structural designers to evaluate the adequacy of current design practices and to investigate the effect of amplitude-dependent damping on the wind-induced responses.
The predicted dynamic responses of the building using the actual amplitude-dependent damping characteristics are compared with those computed by using constant damping parameters assumed by the structural designers or estimated from the field measurements in order to evaluate the adequacy of current design practices and to apply that knowledge to structural design of tall buildings.
The results demonstrate that the new methodology is accurate for estimating the NF and DR of a superhighrise building structure using low-amplitude ambient vibrations data, a complex and challenging task since the measured vibrations signals are noisy and present non-stationary characteristics.
In such an analysis, lateral forces are applied over the height of the building in proportion to the amplitude of the first mode, ϕ1,i and mass, mi, at each floor (i).
The scale of the catastrophe overruled their partiality for sideways glances and unofficial glimpses; their work - blown up to mural size at the New York Historical Society, as if to replace the pulverised, imploded walls of the downed buildings - has an otiose amplitude, an almost obscene beauty.
Conditions that lead to the occurrence of permanent deformations in the building are investigated, and the amplitudes and wavelengths of incident pulses that lead to non-linear response are shown.
For the fundamental building mode, the maximum spectral amplitudes of translational motions on the two horizontal components (Figs. 3(b) and 3(c)) and a small spectral amplitude of rotational motions on the vertical component (Fig. 6(a)) appear at f0 = 0.15 Hz.
