ASSESSING SEISMIC COLLAPSE SAFETY AND RETROFITTING LOW-DUCTILITY RC FRAME STRUCTURES ON THE BASIS OF THE ACCEPTABLE COLLAPSE SAFETY MARGIN IN CHINA

Assessing Seismic Collapse Safety and Retrofitting Low-Ductility RC Frame Structures on the Basis of the Acceptable Collapse Safety Margin in China

The relationship between the average annual collapse probability and collapse safety margin of structures is identified to evaluate Utility Carts structural collapse performance quantitatively.A method is then proposed to determine the acceptable collapse margin ratio (CMR) with a certain annual collapse probability.Two methods, namely adopting ste

One-dimensional time-Floquet photonic crystal

Using the Floquet Hamiltonian derived based on the time-dependent perturbation theory, we investigated Trouser Jeans the quasienergy bands of a one-dimensional time-Floquet photonic crystal (PC).The PC contains two alternating layers with different permittivies in the static case which are labeled as A and B.The permittivity of layer A is modulated

The Role of Bone and Root Resorption on the Biomechanical Behavior of Mandibular Anterior Teeth Subjected to Orthodontic Forces: A Finite Element Approach

Aims: This study was conducted to systematically evaluate the biomechanical impact of varying degrees of root and bone resorption resulting from periodontitis and orthodontic tooth movement (OTM) on the mandibular anterior teeth.The objective was to determine whether these distinct resorption patterns exert a specific influence on tooth displacemen
