To develop the ability to identify and employ strategies of structural system planning, design and configuration of member types, sizing proportions, 1.10'| 80' 110 + Patio pavers 16 bay sizes, and concepts of frame stability, static 48 1 16' on grade evaluations. 1. Structural Planning and Configuration/ System. Problem Statement: A community beach/park center is proposed by a local park district. The park district wants an innovative and showcase structure, they do not want cranes or heavy equipment on the site due to the landscape. The structural system to be considered is a one-way truss system for the roof and wood beams /joists for the floor within a post and beam frame. See images Rest rooms Shower area 12' 64 Main open area (column free space) Elevated wood decking front area to be part of framming system of the floor. Footprint (plan view) 18' min top of roof provided for inspiration only you may vary from the standard types shown. Merit is recognized for solutions with innovation, efficiency, competent structural system planning and correct calculations. The structural material is exterior grade timber/wood material and steel cables or rods that could be used for tension elements. The main pavilion is open below the roof to open it to the outdoors. The roof may Min envelope roof may overhang area shown and be sloped as needed. 8' to ceiling restrooms 24" to finished floor Grade level 0.0 Outline (section view) Concrete footing posts palced as needed have overhangs beyond support columns. The roof may have a skylight in sections or be open to the sky in sections. The floor is a small crawl space with wood flooring. Standard 'dimension lumber' members is limited to a max. length of 20' in length. Glu-laminated timber or wood floor trusses can span longer dimensions. Member Sizing Parameters: Member Sizing Parameters: Bay/truss spacing Spacing = (S) -span S/4 - S/6 Span /depth ratios L/ (#) = member depth trusses are approximately L/10- L/13. Span ranges 24'-200 Wood Beams L/18-L/24 Span range 8-20' Glu-lam beams span range 24'-200 wood decking L/26-L/30 span range 2-4' plywood spans 1'-4' Width/height ratio H/ (#) = col. width Wood Columns H/24- H/26 See the drawing for conditions and parameters. The existing grade is flat. Member and bay repetition is encouraged for economy. The covering for the roof would be a lightweight roofing with plywood (4' x 8' sheets) or wood decking. Secondary elements' joists or purlins rest on primary beams (floor) or trusses (roof). Wood shakes or standing seam metal roofing. The module for structural planning purposes is 4'. The section profile is the minimum interior enclosure, and the exterior shape may vary at the discretion of the student. The design should be a form efficient solution by taking advantage of overhangs and based on the reduction of bending (moment) forces from vertical loads, assume roof loads are uniform. In the main area the Lakefront Kiosk / Ultramoderne Chicago, Competition winner 2015 Webb Chapel Park Pavilion / Cooper Joseph Studio 2012 Texas. Covington Farmers Market / design/build LAB, 2011 Lions Park Scouts / Auburn University Rural Studio, 2014 Jamberoo Farm House / Casey Brown Architecture, 2012 trusses should be shaped and loaded efficiently. Natural light with skylights of clerestory windows is to be part of the system for the upper roof region. The views are to the north and north wall is to be open with glass. The South walls may be largely solid. Both lateral and gravity loads need to be addressed. Use text 250 words maximum to explain your solution. Grading Rubrics: Truss Creativity / Efficiency 20% Beam Calculations 7.5% Graphics (plans, sections, 3Ds, etc.) 30% Truss Calculations 30% Columns Calculations 7.5% Foundations 5% Each student must design to the following conditions Wood post and beam frame system with trusses for the roof and (solid floor beams/joists and solid columns for the floor) "optional". Part 1 Complete the following A. Stability Study- a schematic line drawing section with labeling members, connections, and primary gravity and lateral force components in the short axis section. In long axis, use the truss or frame methods of stability studies.

A short and long structural member section the frame elements bracing and cladding. Suggested scale 1/20' or 1/8". C. Framing Plans Drawings of the roof plan and main level: plan. Draw members to estimated size, shape and profile. Show all members -primary and secondary. In the roof plan, show a cut away section indicating secondary member purlins and roof deck, and sub - flooring, suggested scale 1/20" or 1/8". (Show main floor framing and peel away detail showing the primary/secondary and sub-floor members) "optional". Include exterior deck in the framing plan. D. Trusses must be used in roof for primary members, wood beams or trusses for secondary horizontal members. Post frames would be made of wood columns. Drawings must label all key dimensions, spacing of members, column center lines, and notes on approx. member sizes. Primary Beams or truss framing. Detail of Wood column to foundation. Preferred detail of wood columns is to use double beams that allow columns to provide stiffness in the frame by continuity and create cts. Vertical elements. Split beams allow for smaller beams at outer bays where tributary areas are less. The outer beam carries the weight of the outer wall. A-ow the roof members to straddle the column as the floor beams do at the roof level.
