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.

[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.

API 570-2009 Piping Inspection Code: In-service Inspection, Rating, Repair, and Alteration of Piping Systems
Author: API | Size: 1.15 MB | Format:PDF | Publisher: API | Year: 2009 | pages: 78
1.1 General Application
1.1.1 Coverage
API 570 covers inspection, rating, repair, and alteration procedures for metallic and fiberglass reinforced plastic (FRP)
piping systems and their associated pressure relieving devices that have been placed inservice.
1.1.2 Intent
The intent of this code is to specify the in-service inspection and condition-monitoring program that is needed to
determine the integrity of piping. That program should provide reasonably accurate and timely assessments to
determine if any changes in the condition of piping could possibly compromise continued safe operation. It is also the
intent of this code that owner-users shall respond to any inspection results that require corrective actions to assure
the continued safe operation of piping.
API 570 was developed for the petroleum refining and chemical process industries but may be used, where practical,
for any piping system. It is intended for use by organizations that maintain or have access to an authorized inspection
agency, a repair organization, and technically qualified piping engineers, inspectors, and examiners, all as defined in
Section 3.
1.1.3 Limitations
API 570 shall not be used as a substitute for the original construction requirements governing a piping system before
it is placed inservice; nor shall it be used in conflict with any prevailing regulatory requirements. If the requirements of
this code are more stringent than the regulatory requirements, then the requirements of this code shall govern.
1.2 Specific Applications
The term non metallics has a broad definition but in this code refers to the fiber reinforced plastic groups
encompassed by the generic acronyms FRP (fiberglass-reinforced plastic) and GRP (glass-reinforced plastic). The
extruded, generally homogenous nonmetallics, such as high and low-density polyethylene are excluded. Refer to API
574 for guidance on degradation and inspection issues associated with FRP piping.
1.2.1 Included Fluid Services
Except as provided in 1.2.2, API 570 applies to piping systems for process fluids, hydrocarbons, and similar
flammable or toxic fluid services, such as the following:
a) raw, intermediate, and finished petroleum products;
b) raw, intermediate, and finished chemical products;
c) catalyst lines;
d) hydrogen, natural gas, fuel gas, and flare systems;
e) sour water and hazardous waste streams above threshold limits, as defined by jurisdictional regulations
f) hazardous chemicals above threshold limits, as defined by jurisdictional regulations;
g) cryogenic fluids such as: LN2, LH2, LOX, and liquid air;
h) high-pressure gases greater than 150 psig such as: GHe, GH2, GOX, GN2, and HPA.
1.2.2 Optional Piping Systems and Fluid Services
The fluid services and classes of piping systems listed below are optional with regard to the requirements of API 570.
a) Fluid services that are optional include the following:
1) hazardous fluid services below threshold limits, as defined by jurisdictional regulations;
2) water (including fire protection systems), steam, steam-condensate, boiler feed water, and Category D fluid
services, as defined in ASME B31.3.
b) Other classes of piping systems that are optional are those that are exempted from the applicable process piping
construction code.
1.3 Fitness-For-Service and Risk-Based Inspection (RBI)
This inspection code recognizes Fitness-For-Service concepts for evaluating in-service damage of pressurecontaining
components. API 579 provides detailed assessment procedures for specific types of damage that are
referenced in this code. This inspection code recognizes RBI concepts for determining inspection intervals. API 580
provides guidelines for conducting a risk-based assessment.
