Seismic Design And Evaluation Of Multistory Buildings Using Yield Point Spectra
Author: Edgar F. Black, Mark Aschheim | Size: 5.73 MB | Format:PDF | Publisher: University of Illinois at Urbana-Champaign | Year: 2000 | pages: 222
Seismic Design And Evaluation Of Multistory Buildings Using Yield Point Spectra
Constant ductility response spectra are presented for 15 recorded earthquakes ground
motions using the Yield Point Spectra (YPS) representation. Yield Point Spectra are used for
analysis and design of SDOF structures. The spectra were computed for bilinear and stiffness
degrading load-deformation models, for displacement ductilities equal to 1, 2, 4 and 8.
A methodology for the performance-based seismic design of regular multistory
buildings using Yield Point Spectra is described. The methodology is formulated to make use
of current code approaches as much as possible while allowing the design engineer to limit
the peak displacement response and, to some extent, the peak interstory drift to user-specified
values. To achieve this objective, the design methodology makes use of an equivalent SDOF
model of the building.
A method to estimate peak displacement response and interstory drift indices of
multistory buildings using YPS and establish SDOF formulations is also presented. The
method may be considered a new nonlinear static procedure (NSP). Interstory drift indices
(IDIs) are estimated using deformed shapes of the building based on the first mode shape and
combinations of the first and second mode shapes.

Hello,
I was wondering if someone has these papers.

Currently your field examinations are accurate to about 80 - 85% due to operator error. Momentarily, your field examinations could be 100% accurate, every time. Registered version includes One Point field examinations, grain size charting, the ability to customize the charts, create pivot tables for in depth analysis, custom chart value feedback.
100% Accurate. Excellent training tool for field technicians. Instant results in the field. Act Now!.
[Notes:]
* Test Type: One Point
This form is set to calculate the values of a one point field examination. The values are from the Cylinder compaction and Speedy Moisture methods only. Enter only the Wet Density and the Speedy values. The plots that will appear are the South Carolina Family of Curves and the location of the preceeding values plot relative to the family of curves. The speedy values are automatically converted to oven moisture figures. Only those values that are exactly on a line will calculate to the data table as seen on the SCDOT Family of Curves chart. Any point that lands between two lines will calculate to the average of the preceeding and subsequent proctor values. All calculations are relative to the SCDOT (South Carolina, Department of Transportation) method of 2%. The conversion chart is not necessary for calculations so is purposely left off of the chart for cleanliness.
* Test Type: Proctor
This form is set to calculate the values of a standard proctor examination. The values are from the Cylinder compaction and Oven drying methods only.
* Test Type: Dual Proctor
This form is set to calculate the values of a standard proctor examination and a modified proctor examination. The values are from the Cylinder compaction and Oven drying methods only.
* Test Type: Complete Examination
This form is set to calculate the values of a one point field examination, a standard proctor examination and a modified proctor examination. The One Point values are from the Cylinder compaction and Speedy Moisture methods only. Enter only the Wet Density and the Speedy values. The Standard and Modified proctor values are from the Cylinder compaction and Oven drying methods only.The plots that will appear are a combination of the three examinations. The One Point will show the field results, NOT the field values. The speedy values are automatically converted to oven moisture figures. Only those values that are exactly on a line will calculate to the data table as seen on the SCDOT Family of Curves chart. Any point that lands between two lines will calculate to the average of the preceeding and subsequent proctor values. All calculations are relative to the SCDOT method of 2%. The conversion chart is not necessary for calculations so is purposely left off of the chart for cleanliness.

ANSI/API RP-17A-2006(ISO 13628-1) Design and Operation of Subsea Production Systems—General Requirements and Recommendations
Author: ISO | Size: 4.21 MB | Format:PDF | Publisher: ANSI. API, ISO | Year: 2006 | pages: 242
This part of ISO 13628 provides general requirements and overall recommendations for development of complete subsea production systems, from the design phase to decommissioning and abandonment. This part of ISO 13628 is intended as an umbrella document to govern other parts of ISO 13628 dealing with more detailed requirements for the subsystems which typically form part of a subsea production system. However, in some areas (e.g. system design, structures, manifolds, lifting devices, and colour and marking) more detailed requirements are included herein, as these subjects are not covered in a subsystem standard. The complete subsea production system comprises several subsystems necessary to produce hydrocarbons from one or more subsea wells and transfer them to a given processing facility located offshore (fixed, floating or subsea) or onshore, or to inject water/gas through subsea wells. This part of ISO 13628 and its related subsystem standards apply as far as the interface limits described in Clause 4. Specialized equipment, such as split trees and trees and manifolds in atmospheric chambers, are not specifically discussed because of their limited use. However, the information presented is applicable to those types of equipment. If requirements as stated in this part of ISO 13628 are in conflict with, or are inconsistent with, requirements as stated in the relevant complementary parts of ISO 13628, then the specific requirements in the complementary parts take precedence.

API RP 934-A 2010 Materials and Fabrication of 2 1/4Cr-1Mo, 2 1/4Cr-1Mo-1/4V, 3Cr-1Mo, and 3Cr-1Mo-1/4V Steel Heavy Wall Pressure Vessels for High-temperature, High-pressure Hydrogen Service
Author: API | Size: 1.13 MB | Format:PDF | Publisher: API & ANSI | Year: 2010 | pages: 42
This recommended practice presents materials and fabrication requirements for new 2 1/4Cr and 3Cr steel heavy wall
pressure vessels for high-temperature, high-pressure hydrogen service. It applies to vessels that are designed,
fabricated, certified, and documented in accordance with ASME BPVC, Section VIII, Division 2, including Section 3.4,
Supplemental Requirements for Cr-Mo Steels and ASME Code Case 2151, as applicable. This document may also
be used as a resource when planning to modify an existing heavy wall pressure vessel.
A newer ASME BPVC, Section VIII, Division 3, is available and has higher design allowables, however it has much
stricter design rules (e.g. fatigue and fracture mechanics analyses required) and material testing requirements. It is
outside the scope of this document.
Materials covered by this recommended practice are conventional steels including standard 2-1/4Cr-1Mo and 3Cr-1Mo
steels, and advanced steels which include 2 1/4Cr-1Mo-1/4V, 3Cr-1Mo-1/4V-Ti-B, and 3Cr-1Mo-1/4V-Nb-Ca steels. This
document may be used as a reference document for the fabrication of vessels made of enhanced steels (steels with
mechanical properties increased by special heat treatments) at purchaser discretion. However, no attempt has been
made to cover specific requirements for the enhanced steels.
The interior surfaces of these heavy wall pressure vessels may have an austenitic stainless steel weld overlay lining
to provide additional corrosion resistance. A stainless clad lining using a roll-bonded or explosion-bonded layer on Cr-
Mo base metal may be acceptable, but is outside the scope of this document.
