Steel Design Module 2 - ANSI/AISC 360-16 Standard - AulaGEO

In this session of the Specialized Course in Steel: Special Moment Frames, we delve into a practical exercise using an IP360 profile with two supports and a 10-meter length. Participants will learn to handle permanent loads, plot nominal moment versus unbraced length (Ltb), and calculate demand capacity in terms of moment and shear. The exercise emphasizes the application of theoretical concepts covered in Module 1, using MATLAB software for analysis and verification. Key tasks include local buckling checks, characteristic length calculations, and plotting moment curves for different Cb values. This hands-on module will culminate with an evaluation of the exercise, reinforcing the learned concepts through practical application.

In this lesson of the Steel Specialization Course on Moment-Resisting Frames, we will delve into the practical application of MATLAB software for the design of flexural members. We will begin with an overview of MATLAB, explaining key features and input data relevant to our example. Using a beam with a 10-meter span and specific load conditions, participants will learn to calculate demand moments and shear, create moment diagrams, and understand the importance of consistent units. Detailed instructions will be provided on setting up and running the MATLAB program, ensuring accurate analysis of structural elements according to the AISC 360-16 standard.

In this lesson of the Steel Specialization Course, we will continue our exploration of local buckling in flexural members according to the AISC 360-16 standard. Utilizing MATLAB software, we will demonstrate how the program operates line by line to perform critical calculations and validations. The focus will be on understanding the input data, executing operations to calculate important parameters like the area of the web, moment of inertia, and radius of gyration. We will also review conditions for local buckling in the flanges and web, ensuring they comply with the standards. This lesson provides a practical example to reinforce the theoretical concepts learned in previous classes, guiding participants through the process of using MATLAB to analyze and verify structural elements.

In this lesson of the Steel Specialization Course, we will focus on developing algorithms in MATLAB to calculate characteristic lengths such as Lp (limit length of plastic behavior) and Lr (limit length for lateral torsional and elastic behavior). We will explore the relationship between nominal moment and length Lb, compute key values like the radius of gyration, warping constant, and plastic modulus, and construct the curve of nominal moment versus unbraced length. This lesson provides practical application and reinforcement of theoretical concepts, ensuring a comprehensive understanding of the design and analysis process for steel flexural members.

In this lesson of the Steel Specialization Course, we implement an algorithm in MATLAB to generate two curves: one with a Cb value of 1 and another with a different Cb value. We begin by defining the input parameters and explaining the significance of Lp and Lr, the characteristic lengths. The algorithm calculates and plots the nominal moment versus unbraced length (Lb) for both conditions. Detailed steps, including iterative calculations and conditional statements, are provided to illustrate how MATLAB processes the data to produce the desired curves.

In this segment of the Steel Specialization Course, we continue with our MATLAB algorithm to generate the moment versus length (Lb) curve for a Cb value different from 1. We detail the steps to compute the curve, starting from an initial value of Lbx up to a maximum of 10, considering conditions for Lp and Lr. We discuss the impact of a Cb value of 1.299 on the curve, ensuring it does not exceed the plastic moment. By the end, we compare two curves: one with Cb equal to 1 and the other with Cb different from 1, providing a comprehensive understanding of the moment behavior under varying conditions.
