The object of this paper is the evaluation of the seismic response of reinforced concrete frames designed according to the DDBD (direct displacement-based design) approach. The great part of research works about DDBD has been dedicated to planar frames, but recently also some proposals for 3D structures have been presented, in particular for wall structures. This paper will give a further contr...

The concept of sponge city urbanization construction is the important guiding idea, to quickly eliminate end drainage characteristics traditional urban system; effect very poor under actual extreme precipitation weather conditions. failure system will cause waterlogging and even sewage overflow, thus causing collapse entire water system. In a variety heavy frequency as background, this paper fi...

Abstract A new tool for seismic design is presented, called Yield Displacement Charts (YDC). As with its predecessors, the Point Spectra (YPS) and Frequency (YFS), YDC concept takes advantage of simple features yield displacement ( u y ), to use in a performance-based instead force-based period-dependent approach. self-contained comprehensive approach YPS YFS enabling novel aspect be introduced...

The concept of designing structures to achieve a specified performance limit state defined by strain or drift limits was first introduced, in New Zealand, in 1993. Over the following years, and in particular the past five years, an intense coordinated research effort has been underway in Europe and the USA to develop the concept to the stage where it is a viable and logical alternative to curre...

DNA strand displacement is a key reaction in DNA homologous recombination and DNA mismatch repair and is also heavily utilized in DNA-based computation and locomotion. Despite its ubiquity in science and engineering, sequence-dependent effects of displacement kinetics have not been extensively characterized. Here, we measured toehold-mediated strand displacement kinetics using single-molecule f...

due to business and environmental issues, the efficient design of an integrated forward/reverse logistics network has recently attracted more attention from researchers. the significance of transportation cost and customer satisfaction spurs an interest in developing a flexible network design model with different delivery paths. this paper proposes a flexible mixed-integer programming model to ...

This paper presents a new methodology for the displacement-based seismic design of symmetric single-storey wood-frame buildings. Previous displacement-based design efforts were based on the direct displacement-based design approach, which uses a substitute linear system with an appropriate stiffness and viscous damping combination. Despite the fact that this method has shown to produce promisin...
