Critical Assessment of Estimation Procedures for Floor Acceleration Demands in Steel Moment-Resisting Frames

Frontiers in Built Environment, 2019
Performance-based earthquake engineering has created the need for practical ways to assess the response of non-structural components (NSCs), which may be affected by deformation and/or acceleration demands of the superstructure.

Machine learning-based prediction of moment redistribution in statically indeterminate reinforced concrete flexural members

Discover Civil Engineering
The transfer of moments between critical and non-critical regions is a key behavior in statically indeterminate reinforced concrete (RC) structures, enhancing the utilization of less critical sections and improving the overall ductility and safety of the

Alvaro Mutis and the Ends of History

Studies in 20th & 21st Century Literature, 1995
Part of the confusion of the current literary and critical moment, in Latin America and elsewhere, involves a debate as to whether the most characteristic forms of contemporary writing are the more apparently transparent (in contrast to current critical ...

The Collapse Analysis of the Lateral-Torsional Buckling of I-Shaped Stepped Steel Beams

Journal of the Civil Engineering Forum, 2020
The use of a non-prismatic member such as a stepped beam as a design method has the ability to function as a tool for steel beams optimization. A cover plate is partially welded on the upper and lower flange of the member at the maximum bending moment ...

Open su(4)-invariant spin ladder with boundary defects

, 2000
The integrable su(4)-invariant spin-ladder model with boundary defect is studied using the Bethe ansatz method. The exact phase diagram for the ground state is given and the boundary quantum critical behavior is discussed.

Novel duality in disorder driven local quantum criticality

, 2010
We find that competition between random Kondo and random magnetic correlations results in a quantum phase transition from a local Fermi liquid to a spin liquid.

Evidence of the Poisson/Gaudin-Mehta phase transition for banded matrices on global scales

, 2017
We prove that the Poisson/Gaudin--Mehta phase transition conjectured to occur when the bandwidth of an $N \times N$ symmetric banded matrix grows like $\sqrt N$ is observable as a critical point in the fourth moment of the level density for a wide class ...

Buckling of Double-T Construction Elements for Bridges in Case of Complicated Loading

The Baltic Journal of Road and Bridge Engineering, 2009
This paper analyzes the stability of double-T elements with complicated loading under bending moment and extra torsional moment. In case of simple bending, long elements and elements of small cross-section are under bending and torsion moments.
