Practical Estimates of Site Response in Earthquakes for Seismic-Resistant Design (to the Discussion of SP 14.13330.2014 — the Renovated SNiP II-7-81* “Construction in Seismic Areas”)

Rubric:     Technical regulation and design standards development

Renovated Russian building codes SP 14.13330.2014 “Construction in seismic areas” in sections concerning seismic loadings and soil conditions are discussed.

The updated SP did not change much compared to the previous version SNiP II-7-81*, and the response spectra are simplified. The updated documents do not take into account new knowledge on the manifestations of seismicity, soil behavior during strong earthquakes, and spatial distribution of soils over the territory of Russia, they keep outdated provisions that have already shown their insolvency. The application of one seismic zonation map in the calculations for “project earthquake” and for “maximum credible earthquake” (PZ and MRZ) contradicts to the logic of probabilistic seismic zonation maps OSR-97.

To make the updated SP the documents of a modern scientific level, we should introduce significant changes in them, concerning soil classification, selection of “base” soil type, accounting for soil conditions, application of the method of seismic rigidities (VSZ), and the use of seismic zonation maps OSR-97 for the calculations on PZ and MRZ.

The Seismic Zoning Maps Need Updating

Authors:    Eisenberg J.M.   
Rubric:     Technical regulation and design standards development   

read more

The need of seismic zoning maps deep modification is discussed. The modern seismic maps which are elements of Russian seismic building code are in some parts out of date. The seismic intensity maps are based on different physical intensity criteria. Earthquake ground motions parameters are used simultaneously with human fear estimations. Such criteria use could lead to different estimations of seismic intensities when the real effective intensities of earthquake are equal. Proposals, on seismic intensity criteria modernization and of seismic zoning maps modernization are presented.


Updated are Design Standards «Construction in Seismic Regions» (SNIP II-7-81), on the Agenda are Updating Maps of General Seismic Zoning

Authors:    Eisenberg J.M.   
Rubric:     Technical regulation and design standards development   

read more

When updating a SNIP II-7?81 «Construction in seismic regions» some fundamental changes are made. These changes necessitate changes in the methods, as well as in maps of general seismic zoning (GSZ), which are used in the current regulations. The new updated standards and the old GSZ maps are incompatible.

The paper presents the reasons and examples of this incompatibility. Some suggestions on the expected results for the GSZ update maps of updated design standards «Construction in seismic regions» are also presented.

On the Updated Seismic Zoning Maps of the Russian Federation Territory OSR-97* and OSR-2012

At present within the framework of the Federal Target Program (FTP) «Increasing resistance of dwelling houses, basic life-supporting facilities and systems in seismic areas of the Russian Federation for 2009-2014», the Design Research Institute of Engineering Surveys in Construction (OAO PNIIIS) in cooperation with specialists from the Institute of Physics of the Earth of the Russian Academy of Sciences, carries out updating of seismic zoning maps of the Russian Federation territory. Due to the importance of the country’s seismic zoning, this work needs detailed and comprehensive discussion. This paper deals with scientific discussion of this work results.
It is shown that in making the OSR-97* and OSR-2012 maps, the earthquake engineering data on the regional parameters of seismic wave radiation and propagation on Russia’s territory, being necessary for calculations, were not used. This information is virtually unavailable:  OSR-97* and OSR-2012 maps, as well as previous OSR-97 maps, only one value of quality factor Q~150 at frequency f = 1 Hz is used for the vast territory of Russia, together with the relationships between seismic intensity and peak ground accelerations, obtained for California (USA) - the region with its own features, which are not typical for Russia. All this leads to substantial errors, especially, in mapping under peak ground accelerations.

The problems and scopes of the macroseismic intensity scales are discussed.
The main attention is given to MSK (Medvedev-Sponheuer-Karnik)-scales. Some uncertainties and mistakes in MSK-64 scale are indicated using the seismic upset analysis. These faults make doubtful the results of the scale practical use.
Some proposals are formulated concerning macroseismic scales practical use.
The proposal of waiving the notions and parameters of the macroseismic scale in further development of design codes and standards is discussed.
