GENERAL INTRODUCTION
Structural design is a systematic and iterative process that involves:
1) Identification of intended use and occupancy of a structure – by owner
2) Development of architectural plans and layout – by architect
3) Identification of structural framework – by engineer
4) Estimation of structural loads depending on use and occupancy
5) Analysis of the structure to determine member and connection design forces
6) Design of structural members and connections
7) Verification of design
8) Fabrication & Erection – by steel fabricator and contractor
9) Inspection and Approval – by state building official
Ideally, the owner and the architect, the architect and the engineer, and the engineer and the
fabricator/contractor will collaborate and interact on a regular basis to conceive, develop, design,
and build the structure in an efficient manner. The primary responsibilities of all these players
are as follows:
• Owner - primary responsibility is deciding the use and occupancy, and approving the
architectural plans of the building.
• Architect - primary responsibility is ensuring that the architectural plan of the building
interior is appropriate for the intended use and the overall building is aesthetically pleasing.
• Engineer – primary responsibility is ensuring the safety and serviceability of the structure,
i.e., designing the building to carry the loads safely and ___________.
• Fabricator – primary responsibility is ensuring that the designed members and connections
are fabricated economically in the shop or field as required.

· Complete coverage of elasto-plastic modeling, presenting details of the finite element method, constitutive models, implementation and boundary value application results
· Discusses recent advances in the analysis of porous materials and pressure-dependent materials in more detail than other books currently available
Computational Methods in Elasticity and Plasticity: Solids and Porous Media presents the latest developments in the area of elastic and elasto-plastic finite element modeling of solids, porous media and pressure-dependent materials and structures. The book covers the following topics in depth: the mathematical foundations of solid mechanics, the finite element method for solids and porous media, the theory of plasticity and the finite element implementation of elasto-plastic constitutive models. The book also includes:
-A detailed coverage of elasticity for isotropic and anisotropic solids.
-A detailed treatment of nonlinear iterative methods that could be used for nonlinear elastic and elasto-plastic analyses.
-A detailed treatment of a kinematic hardening von Mises model that could be used to simulate cyclic behavior of solids.
-Discussion of recent advances in the analysis of porous media and pressure-dependent materials in more detail than other books currently available.
Computational Methods in Elasticity and Plasticity: Solids and Porous Media also contains problem sets, worked examples and a solutions manual for instructors.

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.
