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 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 steel braces and

Redox-active tetrathiafulvalene and dithiolene compounds derived from allylic 1,4-diol rearrangement products of disubstituted 1,3-dithiole derivatives

We present a series of compounds by exploiting the unusual 1,4-aryl shift observed for electron-rich 1,3-dithiole-2-thione and tetrathiafulvalene Scouring Pads (TTF) derivatives in the presence of perchloric acid.The mechanistic features of this rearrangement are discussed since this synthetic strategy provides an alternative route for the synthesi
