一、结构安全

1、 Structural safety

1. 强度与稳定性

1. Strength and stability

膜结构看台应具备足够的强度和稳定性，以承受自重、使用荷载以及可能出现的风、雪、地震等自然荷载。设计时需依据相关规范进行结构计算，确保在各种工况下结构不发生破坏或失稳。

The  membrane structure grandstand should have sufficient strength and stability to withstand self weight, usage loads, as well as natural loads such as wind, snow, and earthquakes that may occur. During design, structural calculations must be carried out in accordance with relevant specifications to ensure that the structure does not suffer damage or instability under various working conditions.

2. 连接节点

2. Connect nodes

看台各构件之间的连接节点可靠，能够传递设计荷载。节点设计应考虑便于施工安装，同时保证连接部位具有足够的强度和延性，避免在受力过程中出现节点松动或破坏。

The connection nodes between the components of the grandstand are reliable and can transmit the design load. Node design should consider the convenience of construction and installation, while ensuring that the connecting parts have sufficient strength and ductility to avoid node loosening or damage during the stress process.

二、空间布局

2、 Space layout

1. 视线设计

1. Visual design

看台的布局应保证观众具有良好的视线，能够清晰地观看比赛或演出。合理设计座位排距、升起高度以及视线高差等参数，避免出现视线遮挡。一般来说，后排座位的升起高度应根据前排观众的头顶高度进行计算，确保后排观众的视线不受前排遮挡。

The layout of the stands should ensure that the audience has good visibility and can watch the game or performance clearly. Reasonably design parameters such as seat spacing, lifting height, and line of sight height difference to avoid line of sight obstruction. Generally speaking, the height of the rear seats should be calculated based on the height above the head of the front row audience to ensure that their line of sight is not obstructed by the front row.

2. 疏散通道

2. Evacuation routes

设置合理的疏散通道是保障人员安全的关键。疏散通道应满足一定的宽度要求，且通道应保持畅通无阻，不得堆放明显物品。通道的地面应平整防滑，墙面应设置明显的疏散指示标志，引导观众快速疏散。

Setting up reasonable evacuation routes is the key to ensuring personnel safety. Evacuation routes should meet certain width requirements, and the channels should be kept unobstructed without any items being piled up. The ground of the passage should be flat and slip resistant, and clear evacuation signs should be set up on the walls to guide the audience to evacuate quickly.

三、防火设计

3、 Fireproof design

1. 材料选择

1. Material selection

膜结构看台所使用的材料应具有一定的防火性能。膜材应选用阻燃型材料，其他辅助材料如钢结构构件等也应进行防火处理，以提高整个看台的耐火级限。

The materials used in the membrane structure grandstand should have a certain degree of fire resistance. The membrane material should be made of flame-retardant materials, and other auxiliary materials such as steel structural components should also undergo fire protection treatment to improve the fire resistance level of the entire grandstand.

2. 防火分隔

2. Fire separation

根据看台的规模和功能分区，合理设置防火分隔。例如，不同功能区域之间应采用防火墙、防火卷帘等进行分隔，防止火灾蔓延。同时，应设置火灾自动报警系统和灭火设施，以便及时发现和扑救火灾。

Reasonably set up fire partitions based on the size and functional zoning of the stands. For example, firewalls, fire-resistant rolling shutters, etc. should be used to separate different functional areas to prevent the spread of fire. At the same time, automatic fire alarm systems and firefighting facilities should be installed to detect and extinguish fires in a timely manner.

四、防水与排水

4、 Waterproof and Drainage

1. 防水设计

1. Waterproof design

膜结构本身应具备良好的防水性能，防止雨水渗漏进入看台内部。在膜材的安装过程中，应确保密封良好，避免出现缝隙导致漏水。同时，可以在看台顶部设置排水坡度，引导雨水快速排出。

The membrane structure itself should have good waterproof performance to prevent rainwater from leaking into the interior of the stands. During the installation of the membrane material, it is necessary to ensure good sealing to avoid gaps that may cause water leakage. At the same time, a drainage slope can be set at the top of the stands to guide rainwater to be quickly discharged.

2. 排水系统

2. Drainage system

完善的排水系统是保证看台正常使用的重要环节。排水坡度应符合设计要求，排水管道应畅通无阻，能够迅速排除雨水和其他积水。定期对排水系统进行检查和维护，确保其排水能力。

A complete drainage system is an important part of ensuring the normal use of the stands. The drainage slope should meet the design requirements, and the drainage pipes should be unobstructed and able to quickly drain rainwater and other accumulated water. Regularly inspect and maintain the drainage system to ensure its drainage capacity.

五、声学设计

5、 Acoustic Design

1. 音质要求

1. Sound quality requirements

对于有演出或比赛需求的膜结构球场看台，应进行声学设计，保证良好的音质效果。合理设计看台的形状、材料以及吸声、反射措施，减少回声和噪声干扰，使观众能够清晰地听到声音。

For membrane structure stadium stands with performance or competition requirements, acoustic design should be carried out to ensure good sound quality. Reasonably design the shape, materials, and sound absorption and reflection measures of the stands to reduce echo and noise interference, so that the audience can hear the sound clearly.

2. 声学材料应用

2. Application of Acoustic Materials

在看台内部适当采用吸声材料，如吸音板、吸音棉等，降低声音反射，提高音质清晰度。同时，根据声学原理优化看台的空间布局，减少声音传播过程中的能量损耗。

Appropriately use sound-absorbing materials such as sound-absorbing panels, sound-absorbing cotton, etc. inside the stands to reduce sound reflection and improve sound quality clarity. Meanwhile, based on acoustic principles, optimize the spatial layout of the stands to reduce energy loss during sound propagation.
