A typical Reinforced Concrete (RC) building frame comprising of RC columns and connecting beams that participates in resisting the earthquake forces. Due to earthquake, reversal tension generates at both faces a beam column; hence damage occur for disability carrying capacity concrete. Therefore, structural performance seismic load has been analyzed by nonlinear time history analysis method thi...

In this study, constant-ductility optimization algorithm under a family of earthquake ground motions is utilized to achieve uniform damage distribution over the height of steel moment resisting frames (SMRFs). SMRF structures with stiffness-degrading hysteric behavior are modeled as single-bay generic frame in which the plastic hinge is confined only at the beam ends and the bottom of the first...

A research study was undertaken to assess performance of flat plate systems constructed with slab shear reinforcement under dynamic loads. The research program consisted of shake table tests and accompanying analytical studies of two, approximately one-third scale, two-story, two-bay, slab-column frames. One specimen was constructed with reinforced concrete (RC) slab, whereas the other specimen...

Dantzig-Wolfe decomposition and column generation, devised for linear programs, is a success story in large scale integer programming. We outline and relate the approaches, and survey mainly recent contributions, not yet found in textbooks. We emphasize the growing understanding of the dual point of view, which has brought considerable progress to the column generation theory and practice. It s...

In the title complex, cis-[PtCl(2)(C(11)H(9)N)(2)], the Pt(II) ion is situated in a slightly distorted square-planar environment coordinated by two N atoms from two 2-phenyl-pyridine ligands and two Cl atoms. The two pyridyl planes are inclined with dihedral angles of 59.1 (2) and 61.84 (19)° with respect to the PtCl(2)N(2) plane. In the crystal, the complex mol-ecules display inter- and intra-...

In the crystal structure of the title compound, C(15)H(11)FO(2), mol-ecules form inversion dimers through pairs of weak C-H⋯O hydrogen bonds. Dimers oriented in parallel, linked by C-H⋯π contacts, are arranged in columns along the b axis. The fluoro-phenyl ring and the benzene ring of the 2H-chromen-4(3H)-one unit are inclined to one another by 70.41 (16)°. They are respectively parallel in a g...

In the title compound, C(23)H(27)N(3)O(5), the pyrazole ring is inclined at dihedral angles of 38.16 (6) and 80.80 (6)°, respectively, to the least-squares planes of the benzene and dihydro-pyridine rings. In the crystal, adjacent mol-ecules are linked via a pair of N-H⋯N hydrogen bonds, forming an inversion dimer. The dimers are stacked in a column along the a axis through N-H⋯O hydrogen bonds...

The response of moment resisting frame structures to seismic excitation is strongly dependent on the ability of particular structural members to sustain relatively large inelastic deformations without significant degradation of lateral and axial load-carrying capacity. Conventional reinforced concrete frame structures are typically designed according to the strong column/weak beam concept, whic...
