طريقه التحليل المباشر في تصميم المنشأت المعدنيه هي الطريقة الرئيسية في الاكواد الأمريكيه
AISC-360-10 & AISC-360-16
في الرابط التالي حاولت اختصار ما جاء بها في الكود الامريكي و الطريقه الصحيحة لتطبيق علي برنامج SAP2000

In addition to the attached file, all columns should be divided to four parts using automatic meshing to capture local P-Delta

Direct Analysis Method Applications and Examples
The Direct Analysis Method first appeared in the 2005 AISC Specification for Structural Steel Buildings as an alternate way to design for stability. It was upgraded to Chapter C in the 2010 Specification as the primary method to design structures for stability. For the many engineers transitioning from the Effective Length Method to the Direct Analysis Method, the best way to learn is by example. Using a series of design examples that progress from quite simple to quite interesting, the attendee will leave with a real appreciation for how to apply this relatively new design method.

This course is based on a past AISC Live Webinar.​

#AISC_Design_for_Stability

SteelDay 2013: The Life of the K-Factor
There was a time long ago, in a galaxy not far away, that columns were designed for a length, L, without K. Then, in the early 1960s, the now-familiar K-factor was codified. Over the many decades since, it came to seem as if the K-factor had always existed. Now, we have methods of design by which columns can be designed that take into account stability using KL = L again. This webinar explores the origins and development of K, the effective length factor, and why it often can now be taken equal to 1.

Design for Stability Using the 2010 AISC Specification

What does the 2010 AISC Specification require for stability design and analysis? How does one go about including these requirements in their design? This webinar is an introduction to the methods for incorporating the 2010 AISC Specification requirements into your design. Methods include First-Order Analysis, Effective Length, and the Direct Analysis Method, a method which eschews the need for a K-factor. Important topics that are discussed are member deformations, geometric imperfections, residual stresses and second-order effects.

Five Useful Stability Concepts

A theoretical evaluation of stability requires a second-order analysis in which equilibrium is established for the deflected portion of the structure rather than a typical first-order analysis. This presentation reviews these five important stability concepts:

Loss of stiffness as the buckling load is approached
Inelastic column buckling
Importance of end connection details in built-up columns
Stiffness and strength required for braces
Lean-on bracing systems
This course is based on a past AISC Live Webinar.

A New Approach to Design for Stability

The 2005 AISC Specification contains significant changes to the methods available for stability analysis and design of steel structures. The AISC Specification now includes three methods of analysis: the direct analysis method, the effective length method and the first-order analysis method. This seminar discusses the background to each of these methods, their application to design and the strengths and weaknesses of each design approach.

This course is based on a past NASCC session.

السلام عليكم
هل عن اختيار General 2ed Order فى قائمه ..
Second Order Method
هل لابد من عمل P-Delta Analysis
ام البرنامج بيعملها بناء على الاختيار اعلاه
