Five specimens, representing a typical deficient building column with poor transverse reinforcement detailing and low concrete strength, were tested under cyclic displacement excursions and constant axial load.
The effects of the number of the electron deficient building blocks on the optical absorption, energy levels, charge transport, morphology, crystallinity, and photovoltaic performance of the molecules were investigated.
Four 9-cyanomethylenefluorene derivatives were synthesized as a new class of electron-deficient building blocks for donor acceptor (D A) type alternating copolymers.
The photoactive polymers all contain an electron-deficient building block inspired on the natural indigo dye, bay-annulated indigo, combined with electron-rich thiophene and 4H-dithieno[3,2-b 2′,3′-d]pyrrole 4H-dithieno[3,2-b 2′,3′-d]pyrrole
Our work indicates that naphtho[1,2-c 5,6-c]bis 2-octyl-[1,2,3]triazole) canaphtho[1,2-c 5,6-c]bis 2-octyl-[1,2,3]triazoleock for designaphtho[1,2-c 5,6-c]bis 2-octyl-[1,2,3]triazole.
Despite their efficiency, these natural materials are deficient when building large-scale and high-rise buildings.
FRP retrofit design and analysis of an actual deficient RC building located in Istanbul are presented herein both for the local design spectrum and Duzce ground motion.
Based on the analytical model that was previously verified extensively by comparison with test results, a simplified model was proposed for use in displacement based design of FRPs for deficient RC frame buildings.
The technology consists of installation of a single or multiple sufficient Rocking Cores (RCs) pinned to the foundation and connected to an existing deficient multi-story CBF building to re-distribute seismic forces along its height and create more uniform inter-story drift and ductility demand distributions.
If we are deficient in the fundamental building blocks of organ function, our nerves and muscles and cells aren't going to be functioning at their best.
As precast concrete buildings are deficient in structural continuity, these are more vulnerable to progressive collapse than cast-in-situ RC buildings.
