TechSpan Precast Arches TECHSPAN ARCHES OVERVIEW TechSpan is a buried precast concrete arch. It generally consists of half arch units that meet at the crown, supported by a footing sized for site specific conditions. The backfill around the arch contributes to the resistance of the entire structure, constraining lateral deflections of the arch under vertical loads (soil-structure interaction). Figure: Components of TechSpan arch Zone 3 TechSpan arch units Arch footings Its funicular curve minimizes the tensile forces in the arch, thus creating an axially compressed structure, leading to increased durability and costs savings. This catalogue contains most of the common shapes suitable for roadways, railways and hydraulic applications. With the support of sophisticated Finite Element Method (FEM) analyses, the loads on TechSpan arches are verified for each step of construction including backfilling sequence. Zone 1 Zone 2 The span ranges from about 6m to more than 22m. Height ranges from about 30% to 70% of the span. TechSpan technology results from decades of research and development. The system is designed to accommodate high fills, heavy live loads and altering loading conditions often associated with mining, industrial and railway applications. Cast in-situ crown beam Impermeable membrane and/or geotextile The components defining a TechSpan arch are the following: l Arch footings (cast-in-place or precast); l TechSpan precast arch (male and female arch elements or single piece depending on the transportation limitations); l Cast-in-situ crown beam (for longitudinal connection in the most cases, for stitching the crown in special cases where a 2 pin arch is required); l Waterproofing whenever required or geotextile joint protection; l The backfill (Zone 1, Zone 2 and Zone 3), placed and compacted in layers on both sides of the arch, complying with the Terre Armée Group specifications. * For other configurations, not falling within specified constraints, kindly contact us for assistance.

TechSpan Precast Arches 7 SCOPE AND USE OF THIS CATALOGUE The present catalogue contains most standard shapes suitable for non-hydraulic and hydraulic applications. All the shapes included in the catalogue have been pre-designed considering various parameters hereafter described. The designs herein shall not be used for execution drawings. There are 9 series of shapes, identified by TS-F XXXX: TS for TechSpan arch, F for funicular shape, and XXXX refers to maximum span of each shape (in cm). For each TS-series, several heights can be identified using the subscript with letters from “A” (representing the minimum height of the arch) to “J” (maximum height of the arch). For each product, the catalogue provides the main arch dimensions and the reactions at the footings for several load combinations and various backfill heights. The reactions on foundation are given for the following load cases (refer to section Design Methodology): l Arch SW: erection of the TechSpan arch l BL: permanent full backfill Load l LLA: Live Loads axial l LLE: Live Loads eccentric l SH: 1.0 Seismic horizontal inertial load 0.3 seismic vertical inertial load l SV: 1.0 Seismic vertical inertial load 0.3 seismic horizontal inertial load These reactions, given with no load factor applied, can be used for a preliminary design of foundations. Except during for the erection stage, all reactions are given for 5 overfill heights over the crown (1m, 2m, 3m, 4m, 5m). Hydraulic dimensions of TechSpan shapes are given for the maximum flow rate.

TechSpan Precast Arches DESIGN METHODOLOGY This catalogue contains several pre-engineered series of shapes. Finite Element Model (FEM) analyses have been carried out for each shape using standard soil parameters for a preliminary evaluation of dimensions, internal stresses and reaction on footings. Calculations are carried out for different backfill heights over the crown (ie.: 1m, 2m, 3m, 4m, 5m) and a 5% maximum transverse grade of backfill. A soil density of 20kN/m3 with a friction angle of 30 is considered. The analyses take into account all the construction stages, starting from the erection of the arch to full backfill height. Two live load combinations are considered: an axial and eccentric tandem load l an axial and eccentric distributed load (UDL) l Seismic loadings are considered with two combinations assuming a maximum design acceleration of 0.3g, the first combination with dominant horizontal inertial loads and the second one with dominant vertical inertial loads. For the structural analysis, the following assumptions are taken: l Concrete minimum characteristic cylinder/cube compressive strength of 30/37MPa l Steel minimum yield strength 420MPa l 40mm free cover Further analysis needs to be carried out by the Terre Armée Group, for any other configuration, not covered in this catalogue.

AT TechSpan Precast Arches W SYMBOLS AND DIMENSIONS Span (S) The span of the TechSpan arch is the distance between the inner points of the legs at the base. The maximum span of each TS-series, expressed in cm, gives the name of the shape (for instance TS-F-800 series refers with the maximum span of 8 m). BH AD Height (H) AT W Arch Thickness (AT) Width (W) Arch Development (AD) The arch development is the total length along a cross section from base to base of precast unit. The weight of concrete elements is expressed in ton per unit width to easily identify the WS Backfill Height Over crown (BH) maximum weight and width of pieces The backfill height is the vertical distance according to local restrictions in terms of between the finished grade and top of the maximum dimensions and loads for regular crown at the centerline of the arch. transportation. Width is optimized on a project The catalogue covers heights from 1 to 5 meters. by project basis. WP Contact us to confirm compliance with local requirements O C TO B E R 2 0 1 8 - C o p y r i g h t Te r re A r m é e G ro u p / A l l R i g h t s R e s e r v e d WP Wet Surface (WS) S The height of the TechSpan arch is the maximum vertical distance between the inner point at the crown and the base point of the legs. For each TS-series, the letters from “A” to “J” define different heights of the shape, with a difference in rise of 0,50m. The thickness of the TechSpan arch is constant along the arch development. H WS Used for hydraulic application of TechSpan , the wet surface is the cross sectional area of water flow delimited by the water table and the horizontal line connecting the 2 lower points of the arch legs. For the estimation of the wet surface, a minimum freeboard of 1m between the inner crown point and the water table is considered. Wet Perimeter (WP) Used for hydraulic application of TechSpan , the wet perimeter is the sum of the lengths of each side of the wet surface, excluding the water table, inside of the 2 arch units, and the horizontal line connecting the base of those units. For the estimation of the wet perimeter, a minimum freeboard of 1m between the inner crown point and the water table is also considered. 9

TechSpan Precast Arches 6 TechSpan is a buried precast concrete arch. It generally consists of half arch units that meet at the crown, supported by a footing sized for site speci'c conditions. The back'll around the arch contributes to the resistance of the entire structure, constraining lateral de ections of the arch under vertical
3. Concrete Arches Concrete arches are of two types: Precast concrete block arches In Precast concrete block arches the blocks are cast in molds to the exact shape and size of voussoirs. For key stone and skewbacks special molds are prepared. These will give good appearance because of exact shape and size. Cement concrete of 1:2:4 is used.

A key innovation by Nitterhouse Concrete was the use of bolt-on precast concrete arches. The arches on the main facades were fabricated in individual pieces that were added after the installation of the spandrel panels. The bolt-on precast arches were easily shipped and saved money compared with rounded arch Montclair University Parking Structure
with precast concrete arches. Using precast arches for forming the roof had two advantages. Firstly, it reduced the area of formwork required to form the vertical walls of the gallery. Secondly, the 150mm thick arches required less concrete per lineal metre of gallery than simply supported concrete planks placed across the gallery.
