Steel Fabrication & Erection of Belle Chasse Primary School ET-493 Final Proposal Spring 2015 Instructor: Chris Koutsougeras Advisor: Edward Rode’ Derek Duhon W

Abstract The Belle Chasse Primary School steel fabrication and erection process will theoretically be completed. The pre-design: Design Phase, Site Analysis, Structural Analysis & Code Requirements will be completed during the Spring 2015 semester. Followed by the Fall of 2015 covering the pre-construction phase: Construction Drawings, Building Schedule, Load Calculations, & Cost Estimate.

Introduction Advantages of Steel: Does not wrap or twist – unlike wood. Does not substantially expand and contract with the weather - unlike wood. Does not need time to cure and is immediately at full strength – unlike concrete. Steel is versatile, having more strength with less weight. Steel is of uniform quality with proven durability. Steel has low life cycle costs. Steel is the most recycled material in the United States, being 100% recyclable.

Steel Fabrication This advanced plasma cutting system is called the PythonX. A part file from AutoCAD is loaded into the computer system and the steel is loaded onto the infeed conveyor. It calculates the cutting path, moves the steel into position, & makes all the cuts in one pass.

STEEL ERECTION PROCESS Unload and stage steel in close proximity to work areas. The erection process is divided into phases based on the anticipated movements of the cranes. Columns are erected first, since they are the main support of the structure. Then beams, trusses and the major girders- followed by bracing, stairs and other miscellaneous steel. Plum and bolting consist of placing the steel assemblies in their proper location, aligning them and temporally bolting them in place. Once the majority of the structure is erect, torqueing of bolts and the final welds are completed.

Categorizing structural steel framework into three areas: 1) Main Members- include beams, columns, girders, and trusses. This part of the structure is the main source of support by carrying the primary loads of the structure.

Categorizing structural steel framework into three areas: 2) Secondary Members- include bracing, stairs, and decking. These members are designed to carry a specific load.

Categorizing structural steel framework into three areas: Connections- are joints of structural elements used to transfer forces between structural elements or members. The connections resist the stresses at that point such as – axial loads (compression and ensure tension), bending moments, and torsional loading (torque).

Structural Shapes to be Analyzed

Design Load Specifications Analysis

Code Regulation Analysis Building Code: NFPA Life Safety Code, local & state building codes. Structural steel is that work defined in American Institute of Steel Construction (AISC) "Code of Standard Practice" and as otherwise shown on drawings. This includes fabrication and erection of structural steel work, as shown on drawings including schedules, notes, and details showing size and location of members, typical connections, and types of steel required. Shop drawings prepared under supervision of a Louisiana Licensed Structural Engineer, including complete details and schedules for fabrication and assembly of structural steel members, procedures, and diagrams. Include details of cuts, connections, cambers, holes, and other pertinent data. Indicate welds by standard AWS symbols and show size, length, and type of each weld. All shop drawings used in the field must bear the Architect/Engineer shop drawings review stamp with "No Exceptions Taken" indicated.
