Development of Site-Specific Response Spectra for Seismic Analysis of Concrete Hydraulic Structures Section I Introduction Purpose and Scope This chapter describes procedures for developing site-specific response spectra of ground motions throughout the United States for seismic analyses of hydraulic structures.

Division of Engineering Safety.; Lawrence Livermore National Laboratory.]. This paper presents a practical approach to develop a site-specific design acceleration response spectral (ARS) curve for a soil profile Type F site due to liquefaction. A site development consisted of four main structures up to stories high over a two- to three-level parking structure in Marina Del Ray, California.

Based on the California Building Code (CBC) Cited by: 1. This manual describes the development and use of response spectra for the seismic analysis of concrete hydraulic structures.

The manual provides guidance regarding how earthquake ground motions are characterized as design response spectra and how they are then used in the process of seismic structural analysis and design.

The Uniform Hazard site-dependent response spectrum estimated for return period years almost completely overlaps the Spitak earthquake spectra, that suggests its applicability as the building code's provisions.

At the same time, new building code's response spectrum seems to underestimate seismic loads for periods more than 1 by: 4. the mean site-specific response spectra in Turkey based on data from past earthquakes with the design spectra in AASHTO () and AASHTO () by focusing on the descending part (long period range).

The site-specific response. vi spectra for different soil conditions and magnitude ranges are obtained from strong. The demands on the structures were based on site specific probabilistic response spectra. The site had been subjected to ground motion from two moderate earthquakes from sources near Olympia, Washington in and Peak ground accelerations (PGA) at PSNSY were estimated to have been in the neighborhood of g.

The concept of response spectra was first incorporated into the United States building codes in the late ’s by means of the coefficient Cin the lateral force equation VKCW=by the Structural Engineers Association of California (SEAOC, ), where Vis the total lateral force, Kis a structural systems coefficient oforand Wis the total dead load.

1: The UHRS analysis goal is to achieve site-specific response spectra which reflect the desired exceedance frequencies, or stated another way, preserve the reference site hazard level and result in full site-specific hazard curves for William States Lee III Unit 1.

The response spectrum is developed and iteratively compared to the ARMA model and the site-specific spectrum until a satisfactory match is achieved. Finally, the time domain description of the spectrum-compatible artificial earthquake record is developed exploiting inverse FFT of the design response spectrum.

Response spectra can also be computed for 5% Figure C. Sample uniform hazard and 10% probability of exceedance in 50 years.

Structures subject to earthquake It is similar to a vehicle moving on the ground. In at Caltech, George W. Housner began to publish calculations of response spectra from accelerographs. In the EERI Monograph on "Earthquake Design and Spectra", Newmark and Hall describe how they developed an "idealized" seismic response spectrum based on a range of response spectra generated for available earthquake records.

This was then further developed into a design. New white paper available. Learn more about how the SPECTRA provides a hierarchical–dimensional assessment of psychopathology.

Site-specific response spectra The design spectra such as those presented above were based on earthquake records on alluvium and did not consider soil condition as a parameter.

It is concluded from various studies that soil condition at a site significantly affects the amplifications and shapes as .Chapter 5: Response Analysis for Multi Support Earthquake Excitation Chapter 6: Seismic Soil-Structure Interaction Chapter 7: Non-linear Seismic Response of Structures.

In assessing the site-specific design earthquake characteristics in seismically active zones for performance levels of Collapse Prevention, Life Safety, and Immediate Occupancy that may correspond to 72, and year return period earthquakes, detailed site characterization and site response analyses may be required.
