I have a seminar topic on progressive collapse analysis..so please help me to give any new idea\research topic that I will perform in as a part of seminar or project?

Dear Er. Patel,

We in USA use this document for Design for Prevention of Disproportionate Collapse . This is a U.S. Defense Department Publication.

UFC 4-023-03 14 July 2009 Including Change 2 � 1 June 2013 UNIFIED FACILITIES CRITERIA (UFC)
DESIGN OF BUILDINGS TO RESIST PROGRESSIVE COLLAPSE

Interestingly failure of building RONAN POINT in U.K. started this concept.
British Engineers started this design and we in USA followed them after few years.

SIR CAN YOU PROVIDE COMPLETE PROCEDURE ADOPTED FOR ANALYSIS OF PROGRESSIVE COLLAPSE PHENOMENON

Dear Sefi Engr. ,

Here is the information you ask for . Follow two examples in this document for complete design for Progressive Collapse :

Two Examples ( A Concrete Building or A Steel Building ) in this document you need to go through for complete design for Progressive Collapse :


Appendix � D , A 7-Story Reinforced Concrete Example . Pages : 119-131
Appendix � E , A 4 -Story Structural Steel Example . Pages :132-168 .

Down load this manual of 245 pages and go through these two examples .


Also see this ACI Code requirements for Structural Integrity ( Avoid Disproportionate Collapse ) :


BUILDING CODE REQUIREMENTS FOR STRUCTURAL CONCRETE (ACI 318-14) AND COMMENTARY (ACI 318R-14)
Page � 54 :
CODE COMMENTARY
4.10�Structural integrity
4.10.1 General
4.10.1.1 Reinforcement and connections shall be detailed
to tie the structure together effectively and to improv
overall structural integrity.
R4.10�Structural integrity
R4.10.1 General
R4.10.1.1 It is the intent of the structural integrity requirements
to improve redundancy and ductility through detailing
of reinforcement and connections so that, in the event
of damage to a major supporting element or an abnormal
loading, the resulting damage will be localized and the structure
will have a higher probability of maintaining overall
stability.
Integrity requirements for selected structural member
types are included in the corresponding member chapter in
the sections noted.
4.10.2 Minimum requirements for structural integrity
4.10.2.1 Structural members and their connections shall
按照结构完整性要求ments in
