The phrase "acceleration demand" is correct and usable in written English.
It can be used in contexts related to physics, engineering, or economics where the need for acceleration is being discussed.
Example: "The acceleration demand in the automotive industry has increased due to the push for faster electric vehicles."
Alternatives: "need for acceleration" or "requirement for acceleration".
Because structures with surface foundations are examined, inertial interaction mainly affects the acceleration demand.
The proposed reduction factors are the division of the acceleration demand for the coupled SFS system over the acceleration demand for the free-field, and propose an alternative method to calculate the actual acceleration loading considering interaction effects.
The seismic acceleration loading of structures founded on compliant soil is investigated through numerical elastic time history analyses of coupled soil-foundation-structure (SFS) systems and appropriate reduction factors of acceleration demand for free-field to evaluate acceleration demand for the SFS systems are proposed.
Therefore, the proposed reduction factors clearly demonstrate and quantify the beneficial effect of damping on buildings and bridges, as the maximum average acceleration at the top of the actual SFS system can reduce to about 55 85% of the acceleration demand for the free-field motion.
In current code provisions, the acceleration demand consists of the floor acceleration amplification factor, component acceleration amplification factor, component importance factor, and component response modification factor, which are all based on or induced by the floor response and dynamic response of the CW itself.
Simulations for constant lateral acceleration demands show good tracking with fast response time.
Recommendations are provided to estimate peak acceleration demands for the design of nonstructural components mounted on inelastic frame structures.
Such floor acceleration demands are crucial for the assessment of the seismic performance or vulnerability of dam-supported appurtenant structures.
Two approaches are proposed to obtain floor acceleration demands: analytical and coupled dam reservoir finite element models.
The peak acceleration demands for acceleration-sensitive nonstructural components supported on elastic and inelastic regular moment-resisting frame structures are statistically analyzed.
(the two vertical lines represent the spectral acceleration demands corresponding to the MCE hazard level for seismic zones IV and V, respectively).
