Comparison of Base Shears Estimated from Floor Accelerations and Column Shears
نویسنده
چکیده
This paper compares base shears computed from floor accelerations (inertial base shear) and column shears (structural base shear) for two mid-rise, multi story buildings due to a suite of 30 earthquake ground motions. The presented results demonstrate that the inertial base shear exceeds the structural base shear in the median by 10% to 20% and may exceed the structural base shear by as much as 70% fOr individual ground motions. Therefore, it is concluded that the inertial base shem computed 1iom strong motion records should be used with caution to estimate the structural base shear. [DOT: 10.1193/1.361 0247]

Base Shear Estimated from Floor Accelerations and Column Shears
This paper compares base shear computed from floor accelerations (inertial base shear) and column shears (structural base shear) for several single-degree-of-freedom (SDF) systems and two mid-rise, multi-story buildings due to a suite of 30 earthquake ground motions. The presented results show that the inertial base shear is close to structural base shear in short-period (<1 sec) SDF systems bu...
متن کاملEvaluation of Nonlinear Response of Structures to Near-Fault Ground Motions and the Comparison of Results with Near-Fault Simulated Records
Near-fault ground motions have caused very much damage in the vicinity of seismic sources during recent earthquakes. It is well known that under specific circumstances, intensive ground shakings near fault ruptures may be characterized by short-duration impulsive motions. This pulse-type motion is generally particular to the forward direction, where the fault rupture propagates towards the site...
متن کاملLaparoscopic-Assisted Colectomy: A Comparison of Dissection Techniques
BACKGROUND AND OBJECTIVES Mobilization of the colon and dissection of the mesentery are difficult laparoscopic techniques. Traditional methods have been used for this dissection, but often with great difficulty. The ultrasonically activated shears, when introduced in 1993, had the possibility to make this dissection less technically difficult. This is a retrospective review of the use of these ...
متن کاملConvex combinations of harmonic shears of slit mappings
In this paper, we study the convex combinations of harmonic mappings obtained by shearing a class of slit conformal mappings. Sufficient conditions for the convex combinations of harmonic mappings of this family to be univalent and convex in the horizontal direction are derived. Several examples of univalent harmonic mappings constructed by using these methods are presented to illustrate...
متن کاملAAPG Annual Meeting 2013 INFLUENCE OF PRE-EXISTING STRIKE-SLIP FAULTS ON FAULT DEVELOPMENT DURING SUBSEQUENT PHASES OF DEFORMATION
We used scaled experimental (analog) models with wet clay to investigate how conjugate sets of steeply dipping strike-slip faults affect deformation patterns during a subsequent phase of extension. In all twophase experiments, an initial phase of strike-slip deformation produces a long, wide deformation zone consisting of subvertical Riedel shears; synthetic R-shears and antithetic R'-shears tr...
