Optical Instrument Survival In A Major Earthquake [PDF]

, 1980
Many organizations presently are evaluating the potential loss to plant, equipment and production capability in event of a major earthquake in their area. Often it is found that equipment can be protected at a fraction of the replacement cost.

Design on the Shaking Table Test for Ground Crack Dynamic Response under Earthquake

Chemical Engineering Transactions, 2016
In this paper, according to a particular ground fissures in Xi’an city in the south of the actual stratigraphic profiles use a similar role of strong earthquakes and the theory of vibration table crack mechanical response model test for similar relation design. Find out the model of soil physical and mechanical parameters.

Evaluation of the Adequacy of Design Specifications for Nonstructural Components in a Reticular Structure

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Nonstructural components (NSCs) installed in large‐span reticular structures were frequently severely damaged during earthquakes, even when the primary structure remained intact. Existing seismic design specifications for NSCs were predominantly developed for upright structures such as multi‐storey buildings and offer no guidance for reticular

Assessment of foundation damage during earthquakes using acoustic emission monitoring: An experimental study on the shaking table test

Soils and Foundations
Assessing structural foundation damage following an earthquake is critical for safety evaluation. However, assessing the damage to pile foundations with traditional visual inspections and non-destructive testing methods is challenging.

Dynamic Characteristics of Woodframe Buildings [PDF]

, 2002
The dynamic properties of wood shearwall buildings were evaluated, such as modal frequencies, damping and mode shapes of the structures. Through analysis of recorded earthquake response and by forced vibration testing, a database of periods and damping ...

Shaking Table Tests and Numerical Analysis of Rocking Vault‐Shaped Segmental Piers Equipped With an Annular Double Sliding System

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT To enhance the structural robustness of bridges, a rocking arch‐shaped segmental pier with a double sliding system was previously proposed as a low‐cost solution to protect bridges in developing countries. The rocking behavior is triggered by halting the sliding motion, which increases the horizontal load‐bearing capacity and limits ...

Centrifuge shaking table tests on evolution mechanism of sand mesostructure during earthquake liquefaction

Yantu gongcheng xuebao, 2022
The existing studies demonstrate that the history of earthquake liquefaction is an important factor affecting the liquefaction resistance of sand. The researchers think the intrinsic mechanism of these effects is the generation of stable or unstable sand

Coupled Fluid–Structure–Acoustic Analysis of Flow‐Induced Noise Control Using an Elastic Baffle in a Micro Channel

Energy Science &Engineering, EarlyView.
This research explores how fluid flow, structural movement, and sound interact in an elastic baffle system. Using a numerical approach based on the finite element method, the study analyzes how noise and vibrations change with different baffle configurations. The findings reveal that shortening the baffle by half reduces noise transmission by 9%, while

Source parameters of the great Sumatran megathrust earthquakes of 1797 and 1833 inferred from coral microatolls [PDF]

, 2006
Large uplifts and tilts occurred on the Sumatran outer arc islands between 0.5° and 3.3°S during great historical earthquakes in 1797 and 1833, as judged from relative sea level changes recorded by annually banded coral heads.
