Stand for a stadium, and a method for determining the stand configuration
The present disclosure relates to a stand for a stadium. The stand comprises, a plurality or rows, each row containing a plurality of seats, and a structure having a width and a depth, wherein the plurality of rows of seats are mounted to the structure. The cross-sectional profile of the structure along the direction of the depth of the structure varies along the direction of the width of the structure such that a C-value for each of the plurality of seats is configurable. In a preferred embodiment, the C-value is configured to be substantially constant. A method of configuring the arrangement of such a stand is also disclosed.
1. A stand for a stadium, comprising: a plurality of rows, each row containing a plurality of seats; and a structure having a width and a depth, wherein the plurality of rows are mounted to said structure; wherein, a cross-sectional profile of the structure along a direction of the depth of the structure varies along a direction of the width of the structure in the form of a parabola such that a C-value for each of the plurality of seats is configurable within 5% of an average C-value, wherein the C-value for each seat is defined as the vertical distance between a sight-line of a first spectator in one of said plurality of seats, and an eye level of a second spectator sitting in another one of said plurality of seats, directly in front of the first spectator; wherein said average C-value is calculated from all seats from said plurality of rows.
2. A stand according to claim 1 , wherein, the cross-sectional profile of the structure along the direction of the depth of the structure varies from a first parabolic profile at a first end of the stand to a second parabolic profile at a centre of the stand.
3. A stand according to claim 2 , wherein the cross-sectional profile of the structure along the direction of the depth of the structure varies from the second parabolic profile at the centre of the stand to a third parabolic profile at a second end of the stand.
4. A stand according to claim 3 , wherein the first parabolic profile and the third parabolic profile are substantially the same.
5. A stand according to claim 1 , wherein an angle of rake of the seats at a first end of the stand is θ, and an angle of rake of the seats at a centre of the stand is α, wherein θ is greater than α.
6. A stand according to claim 1 , wherein the cross-sectional profile of the structure along the width of the structure of at least one of the plurality of rows is parabolic.
7. A stand according to claim 1 , wherein a top row of seats lies in a plane substantially parallel to the plane containing a field of play.
8. A stand according to claim 1 , wherein a bottom row of seats lies in a plane substantially parallel to the plane containing a field of play.
9. A stand according to claim 1 , wherein the side of the stand adjacent a field of play is curved when viewed in plan.
10. A stand according to claim 1 , wherein the side of the stand adjacent the field of play is straight when viewed in plan.
11. A method of configuring a stand for a stadium, the stand comprising a plurality of rows, each row containing a plurality of seats, and a structure having a width and a depth, wherein the plurality of rows of seats are mounted to said structure, the method comprising: determining a required C-value for each seat in the stand, wherein the C-value for each seat is defined as the vertical distance between a sight-line of a first spectator in one of said plurality of seats, and an eye level of a second spectator sitting in another one of said plurality of seats, directly in front of the first spectator; determining a cross-sectional profile of the structure along a direction of the depth of the structure at a centre of the stand, such that each seat in the cross-section has a substantially constant C-value within 5% of an average C-value; determining a cross-sectional profile of the structure along the direction of the depth of the structure at a first end of the stand, such that each seat in the cross-section has a C-value substantially equal to the constant C-value within 5% of said average C-value; determining a cross-sectional profile of the structure along the direction of the depth of the structure at a second end of the stand, such that each seat in the cross-section has a C-value substantially equal to the constant C-value within 5% of said average C-value; and varying the cross-sectional profile of the structure between the first end of the stand and the centre of the stand using a parabolic cross-section, and between the second end of the stand and the centre of the stand, such that the C-value for each seat in the stand is substantially constant within 5% of said average C-value; wherein said average C-value is calculated from all seats from said plurality of rows.
