lternative Approaches to Connecting Speedcore Modules to Simplify Construction

Brief 

This article discusses alternative approaches to connecting Speedcore modules to simplify construction. The proposed methods reduce the amount of field welding and simplify the connections at the interfaces between individual wall modules. This could lead to cost savings and faster construction times.

 

Insight

The SpeedCore system is a modular construction system that uses steel faceplates, concrete infill, and tie bars to create shear walls. It is a viable alternative to conventional reinforced concrete shear walls, and it has been used in several high-rise buildings in the United States.

One of the advantages of SpeedCore is that it can be prefabricated off-site, which can lead to faster construction times. However, the traditional method of connecting Speedcore modules requires field welding, which can be time-consuming and expensive.

This article proposes alternative approaches to connecting Speedcore modules that reduce the amount of field welding and simplify the connections. These methods are based on AISC and ACI standards, and they are currently being verified through experimental testing.

The proposed alternative approaches could lead to cost savings and faster construction times for SpeedCore projects. They could also make SpeedCore a more attractive option for builders in areas with high seismic demand.

Here are some additional details about the proposed alternative approaches:

• The modules could be oriented vertically, with horizontal joints at every two to three floors. This would reduce the number of horizontal joints, which are structurally more demanding than vertical joints.
• The modules could be connected using fillet welds or bolted splices instead of CJP welds. These connections are less expensive and easier to inspect than CJP welds.
• The faceplates of the modules could be made thinner, which would reduce the amount of steel required. This would also make the modules lighter and easier to handle.

The proposed alternative approaches to connecting Speedcore modules have the potential to make SpeedCore a more cost-effective and efficient construction system. They are currently being verified through experimental testing, and they could be implemented in future SpeedCore projects.
