The development of strong and stiff lateral load-resisting systems (LLRS) is essential for mid-rise high-rise timber buildings. On the other hand, within a seismic design philosophy, strength/stiffness ductility/drift capacity typically appear as opposite target parameters, depending on acceptable level damage. For improved stiffness strength, core-wall tubular structural forms commonly are use...

Pre-stressed members in various structures are gaining popularity among engineers many parts of the world because pre-stressed strands offer better stability, serviceability, economy, aesthetics, and structural efficiency. The profile strand greatly influences tensile strength concrete. force exerted by on concrete counterbalances internal forces. A construction engineer’s principal goal is to ...

Abstract A new self-centering concrete bridge column has been developed by the authors. The proposed uses unstressed partially unbonded seven-wire steel strands as elastic elements to reduce residual displacement of after a strong earthquake. This research aimed study effect cover thickness ratio on cyclic behavior column. Four large-scale specimens were tested using lateral loading. One was co...

We propose and test a pair potential that is accurate at all relevant distances and simple enough for use in large-scale computer simulations. A combination of the Rydberg potential from spectroscopy and the London inverse-sixth-power energy, the proposed form fits spectroscopically determined potentials better than the Morse, Varnshi, and Hulburt-Hirschfelder potentials and much better than th...
