SPECIFICATIONS FOR ARCH TYPE BUILDING SYSTEMS

**Note: These specifications are designed to be used as a general guideline when preparing performance specifications for arch type building systems.

1.0 Scope

This section covers the design, material, fabrication, shipment and erection of arch based building systems. All material, erection and field work included and excluded shall be in accordance with the "Code of Standard Practice" of the building construction industry.

2.0 Description

All the various models of buildings listed below utilize the basic bolted arch panel concept to form spans of various shapes. The pre-punched panel bolted construction can be utilized for permanent structures or be easily dismantled for reassembly with virtually no damage to the members. This portability is an added feature not normally encountered in the pre-engineered building field.

2.1 Building Size

Building sizes range from 10' wide spans in our Mini models up to unlimited widths in our "multi-span" arch systems. Lengths are unlimited, based on 18" increments for the Mini building and 2'-0" for all other models. Peak heights and sidewall clearances vary for different model types and cover a wide range of combinations.

2.2 Building Type

(A) Basic Models A single radius clear span arch structure. Standard sizes range from 19' wide to 100' wide with height being limited to 1/2 span or less. (B) Open Sided A single radius, partial arch structure, clear span with structural frame supports on open side. Standard sizes range from 19' wide to 50' wide with open side clearances of 8', 10', 12', 14', 16' and varying bay spacings. (C) S Series A straight sided, multiple radius clear span arch system. Standard sizes range from 20' wide to 50' wide, with straight sides and varying center heights. (D) Econospan A straight roof, straight sided clear span building system with a uniform roof slope of 18 degrees. Standard sizes range from 20' wide to 30' wide with varying center heights. (E) Support Arch A single radius, arch structure with interior center column support system. Standard sizes range from 80' wide to 120' wide with varying center peak heights. (F) Roof Systems A single radius clear span low profile arch structure designed to act as a roof system utilizing conventional wall designs as sidewall support. Standard sizes range from 30' wide to 90' wide with heights in the 10' to 30' region. (G) Multiple Arch Spans A series of single radius arch structures sharing a common structural support system as an interior wall. Standard sizes range from 30' to 70' wide for each individual span, joined side by side in any number of combinations from double span to triple span and upward. (H) Conveyor Covers Either single radius or multiple radius clear span arch structures designed to cover standard single or double conveyors and acting as a gallery. Standard sizes range from 10' wide to 30' wide with heights and sidewall clearances to accommodate any combination of conveyor and walkway systems. (I) Mini Buildings (Security Shelters) Single radius clear span arch structure with straight sides. Designed to provide tamper proof, secure cover for remote storage locations such as well-head valves, oil field storage, etc. Standard sizes range from 10' wide to 20' wide with various peak heights to suit different applications.

2.3 Arch Structures

All arch structures, other than Mini Buildings, utilize our standard 2'W X 10'L corrugated prepunched panels as the basis of the design. Panels are cold formed to various radii as required and bolted together to achieve the desired span. Panels are gang punched to ensure uniformity of manufacture and ease of assembly.

2.4 Endwall Systems

All endwalls are designed using our standard 18" center 3 1/4" deep corrugated, prepunched panels to form various endwall arrangements as required. By altering the pattern of panels any size opening can be achieved to accommodate roll-up, overhead, swing or sliding door systems.

2.5 Building Loading
