Assessment of Near-Fault Ground Motion Effects on the Fragility Curves of Tall Steel Moment Resisting Frames
Nowadays it is common to use the fragility curves in probabilistic methods to determine the collapse probability resulting from an earthquake. The uncertainties exist in intensity and frequency content of the earthquake records are considered as the most effective parameters in developing the fragility curves. The pulse-type records reported in the near-fault regions might lead to the major dam...
متن کاملResponse of Buildings with Inclined First-Story Columns to Near-Fault Ground Motion
In this paper a simple model of a three story building with inclined first-story columns has presented. The stories are supposed to be rigid and are connected to axially rigid mass less columns by elasto-plastic rotational springs and linear rotational dampers. The considered model is subjected to horizontal component of fault normal pulse with different magnitudes and the governed nonlinear di...
متن کاملSelection of Optimal Intensity Measure for Seismic Assessment of Steel Buckling Restrained Braced Frames under Near-Fault Ground Motions
Buckling restrained braces (BRBs) have a similar behavior under compression and tension loadings. Therefore, they can be applied as a favorable lateral load resisting system for structures. In the performance-based earthquake engineering (PBEE) framework, an intermediate variable called intensity measure (IM) links the seismic hazard analysis with the structural response analyses. An optimal IM...
متن کاملSeismic Fragility Assessment of Steel SMRF Structures under Various Types of Near Fault Forward Directivity Ground Motions
In this paper, the seismic collapse probability of special steel moment-resisting frame (SSMRF) structures under near fault pulse-like and far fault ordinary ground motions is evaluated through fragility analysis. For this purpose, five sample frames with 3 to 15 stories are designed and imposed to the ground motion excitations with different characteristics. Fragility curves are derived for th...
متن کاملDeflection Measurement of Masonry Arch Bridges with Tall Piers: Case Study of Shahbazan Bridge
A common practice for detailed assessment of masonry bridges is to use recorded deflection signature of mid-span of such structures due to predefined loading schemes. However, measuring the deflection of bridges with tall piers or those situated over deep valleys introduces certain difficulties, since common deflection-meters require a reference point relative to which the measureme...
