Seismic Analysis Capability in NASTRAN [PDF]

open access: yes, 1984
Seismic analysis is a technique which pertains to loading described in terms of boundary accelerations. Earthquake shocks to buildings is the type of excitation which usually comes to mind when one hears the word seismic, but this technique also applied ...

A Bottom‐Up Design Framework for Multifunctional Lattice Metamaterials

open access: yesAdvanced Science, EarlyView.
This study introduces a generative AI framework for designing multifunctional lattice metamaterials. The method combines 3D Gaussian voxel generation with deep learning, enabling greater design freedom and structural performance. The optimized lattice metamaterials achieve enhanced energy absorption by 40–200% compared to conventional structures and ...

An earthquake response spectrum method for linear light secondary substructures [PDF]

open access: yes, 2007
YesEarthquake response spectrum is the most popular tool in the seismic analysis and design of structures. In the case of combined primary-secondary (P-S) systems, the response of the supporting P substructure is generally evaluated without considering

Effective linear damping and stiffness coefficients of nonlinear systems for design spectrum based analysis [PDF]

open access: yes, 2010
A stochastic approach for obtaining reliable estimates of the peak response of nonlinear systems to excitations specified via a design seismic spectrum is proposed. This is achieved in an efficient manner without resorting to numerical integration of the

Active Metamaterials with Tunable Shear Nonreciprocity and Nonlinear Dynamics

open access: yesAdvanced Science, EarlyView.
Active gear‐based mechanical metamaterials enable simultaneous control of translational and torsional stiffnesses by 30–100×, break shear reciprocity under positive versus negative loads, broadly tune resonant frequencies, and offer programmable dynamic responses.

Quality and co-seismic response analysis of static water level in Dehongfapa well

open access: yes地震科学进展
Using static water level observation data from Dehongfapa well and recorded co-seismic response events as the research objects, the operation, tidal factor, observation accuracy, and co-seismic response characteristics of the static water level ...

Modal seismic analysis of a nuclear power plant control panel and comparison with SAP 4 [PDF]

open access: yes, 1976
The application of NASTRAN to seismic analysis by considering the example of a nuclear power plant control panel was considered. A modal analysis of a three-dimensional model of the panel, consisting of beam and quadri-lateral membrane elements, is ...

Challenges and Opportunities in Multi‐Method Integrated Geophysical Prospection of Buried Building Remains at the Sanctuary of Olympia

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Ancient Olympia was one of the most important sanctuaries and the venue for the Olympic Games in Greek and Roman times. Its remains are located in the Olympia Terrace (Peloponnese, Greece) at the present‐day confluence of the rivers Alpheios and Kladeos at the base of Mount Kronos.

Seismic response of small-radius planar curved tunnels

open access: yesYantu gongcheng xuebao, 2019
A three-dimensional model for small-radius planar curved tunnels with different bending angles is established to investigate their seismic response. The influences of bending angle, amplitude and type of ground motion are considered. The seismic response

Sequencing Finance for Climate Resilience: Instruments, Institutions and Hong Kong's Role in Mobilising Private Capital in Southeast Asia

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This paper investigates innovative financing strategies to mobilise private capital for climate adaptation, emphasising Hong Kong's role in advancing efforts across Southeast Asia. Using expert interviews and case studies, it addresses two key questions: which financial instruments can strengthen public–private collaboration, and what best ...
