** Moment Redistribution For Continuous Steel Beams.**

This is the 29th post of the **steel beam posts-part-4**, which includes a brief discussion of the statically indeterminate beams, where we will have both positive and negative moments and the methods we will use. We will review table-3-23 for continuous beam shear and moment values, redistribution of the moment, elastic redistribution, and 0.90 of the largestโve moment.

This is a link to post 29-**Moment Redistribution**.

** Introduction to design of continuous beam, problem 4-15.**

This is the 30th post of the **steel beam posts-part-4, **which includes a solved problem from Prof. Alan Williams’s book. Solved problem 4-15 Moment Redistribution. The uniform distributed loading, including the beam self-weight, acting on a two-span continuous beam, is shown in Fig. 4.16. Continuous lateral support is provided to the beam.

Determine the lightest adequate W10 section using steel with a yield stress of 50 ksi.

**Collapse load for a simply supported beam.**

This is the 31st post of Steel beam Posts-part-4, which includes a solved problem, how to determine the plastic moment, and the collapse load value for a beam that is fixed at one end and has roller support at the other end. The beam is loaded by a concentrated load.

**Easy illustration for collapse load for indeterminate beam.**

**Easy illustration for collapse load for indeterminate beam.**

This is the 32nd post of the **Steel beam Posts-part-4,** which includes a solved problem, how to determine the plastic moment, and the collapse load value for a beam fixed at one end and with roller support at the other end, loaded by a concentrated load.

This is the link for post 32: the Collapse load for the indeterminate beam.** **

**Upper bound and lower bound definitions.**

Here are two posts,33 and 33a-The two posts are among the Steel beam Posts-part-4, which includes the definitions of the lower bound & upper bound and the unique theorem. How to determine the relationship between the load factor and the distance from support for the same solved problem included in the previous post.

This is the link for post 33: the Upper and lower bound definitions.

This is the link for post-33a: Step-by-19 step introduction to lower bound and uniqueness.

**Plastic Moment For Continous Beams.**

This is the 34th post of Steel beam Posts-part-4, which includes determining the plastic moment and the collapse UL load for a continuous beam with equal spans. Two methods are used: the statical method, or the lower bound method, and the Mechanism method, or the upper bound method.

This is the link for post 34: **Plastic Moment For Continous Beams.**

For posts from post 35 to post 37, A mastan2 solution is included to verify our estimations.

**Solved Problem 8-22 For Plastic Moment.**

This is the 35th post of Steel beam Posts-part-4, which includes a solved problem: How to determine the collapse load value for a beam that is fixed at both ends and loaded by a concentrated load? Two methods are used: the first method is the statical method or the lower bound method, and the second method is the Mechanism or the upper bound method.

**Solved problem 8-32 for the plastic Nominal Uniform load.**

This is the 36th post of Steel beam Posts-part-4, which includes a solved problem: How can the collapse uniform load value for a given section of a simple beam partially loaded and fixed at both ends be determined?

The problem was further modified; the uniform load was relocated, and the two methods again estimated the plastic nominal uniform load. This is the link for post 36: Solved problems** ****8-32****.**

Solved problems 8-33&34 for the nominal uniform load.

There are two posts,37 and 37a. These two posts are part of the s**teel beam Posts-part-4,** which includes two solved problems, 8.33 and 8-34.

. Using the given section, all of the A992 steel and the plastic theory, for the first problem 8.33- determine the value of Wn as indicated for a continuous beam with varying loading.

For the second problem, #.8.34, determine the value of Wn as indicated for a continuous beam fixed from both ends under Wn loads.
