Rooftop tower

Rooftop cell towers

Rooftop structures are a popular solution for providing elevation to install antennas, especially in urban or densely populated areas where traditional tower structures may not be feasible. These structures come in various types, such as rooftop towers, rooftop poles, rooftop poles with bracing, and rooftop guyed poles.

Rooftop towers are usually self-supporting structures that are installed on the rooftop of buildings. They are easy to install and maintain, and their height can be customized according to the requirement. Rooftop poles, on the other hand, are lightweight and can be easily mounted on the rooftop or walls of buildings. 

Rooftop poles with bracing provide additional support and stability to the structure, making them suitable for larger and heavier antennas. They can also be used in areas where high winds or seismic activity is a concern. Rooftop guyed poles use a system of struts to provide additional support and stability. They are suitable for taller structures and can be used for applications such as radio and television broadcasting.

The advantages of using rooftop structures include their ease of installation, low cost, and minimal impact on the surrounding environment. They also provide a practical solution for operators who need to install antennas in urban or densely populated areas. Rooftop structures can be installed quickly, and they require minimal foundation work, making them a cost-effective option as rooftop structures do not take up valuable ground space, which is especially important in crowded urban areas.

Telecom towers with strut brace

ASMTower is able to design rooftop masts and poles with struts and bracing members to optimize the capacity and reduce their buckling length of strut members.
The software automatically calculates wind load on all structure components and perform P-delta analysis and designs all structure’s members, including struts, bracing, and connections, ensuring that design is safe and compliant with industry standards.
With its advanced finite element analysis techniques, ASMTower can model complex geometries and simulate the behavior of the structure under different loading conditions, providing designers with accurate and reliable results.
ASMTower is a valuable tool for designers looking to create safe, efficient, and cost-effective rooftop mast designs that meet industry standards and comply with safety regulations.

Non-penetrating roof mount and tower

ASMTower is able to design non-penetration bases for rooftop masts and poles. It is capable of performing all required stability checks, including overturning and sliding checks, while taking into consideration the effect of base uplift when the strut is subjected to tension force which can greatly affect the members’ design and rating.

ASMTower user can easily add and modify the number, dimension and density of counter blocks and instantly takes its effect in the design.

User can also define the allowable stress capacity for the roof, it is important to consider the load that will be imposed on the roof by the mast or pole that shall not be exceeded for not only the mast or pole itself but also any additional equipment that will be mounted on it, such as antennas or cameras.

Antenna Wall Mount

Antenna wall mount is a type of mounting system used to attach an antenna to a wall. It is commonly used in situations where it is not possible or desirable to mount the antenna on the roof area of elevated structure. The wall mount typically consists of a bracket or other support structure that is attached to the wall using bolts or other fasteners. 

ASMTower  can be used to design antenna wall mounts and determine the strut reaction while considering bending moment to ensure that the wall mount is able to withstand the forces that will be imposed on it by the antennas.

By using ASMTower to design the wall mount, it is possible to optimize the design for antenna wall mount, ensuring that it is safe, stable, and durable.

ASMTower Output

  • ASMTower provides a detailed 3D view of the tower, including members and appurtenances, allowing for easy checking of input data and reducing the risk of errors.
  • The software also color members based on their utilization ratio, helping users identify unsafe sections of the tower.
  • Additionally ASMTower generates valuable charts and diagrams, such as deformation conditions, displacement, tilt and twist, and global bending moment and shear diagrams, with the ability to show deformed shapes at various wind directions and load combinations.
  • Users can also generate comprehensive output reports in RTF format, with the ability to adjust report settings and select specific components to be included in the report.
