Space truss structure is a major type of spatial grid system. It is a spatial bar structure composed of members arranged regularly and connected via joints. It is mainly designed as double-layer or multi-layer flat grids, differing from single-layer latticed shells.
Space truss structures are commonly adopted for roof structures, mostly in single-layer and flat shapes. They are widely used in public buildings including កន្លែងហាត់ប្រាណ, សាលតាំងពិពណ៌, កន្លែងរង់ចាំស្ថានីយ៍និងស្ថានីយអាកាសយានដ្ឋាន. In recent years, they have also been applied to industrial buildings such asឃ្លាំងរោងជាង និងរោងជាងរោងចក្រ។ Boasting diversified advantages, they stand out as a mainstream option for large-span public buildings.

Space truss structures easily achieve column-free coverage ranging from 60 to 150 meters, creating fully open and spacious interiors. Beijing Capital Gymnasium adopts space truss structure with a span of 99 meters by 112.2 meters. This advantage makes space truss the mainstream choice for airport terminal roofs.

Shenzhen Bay Sports Center combines single-layer latticed shell and double-layer curved truss, both serving as iconic architectural examples.
The selection of space truss structure is comprehensively determined by factors including building planar shape, architectural requirements, load, span, support condition and construction cost.
Overall, adopting space truss structures enables creating larger spaces with fewer materials. Against the backdrop of high-quality development and green construction, space truss serves as the solid framework backbone of large-span public buildings.
