Structural Design of Philippine Arena

Abstract

The Philippine Arena Project is a large domed roof structure. The arena volume is significant, with 227 m × 179 m ellipse shaped space standing, which is the largest non-column arena in the world. Reinforced concrete is used for the bowl structure and main seismic resisting system is considered as dual system. For the structure above Level 04, steel rakers and columns are applied. To identify seismic resisting performance of steel structure, push over analysis had been carried out. Pre-cast concrete plank is planned for arena seating to meet constructing ability. The roof structure is grid type space frame. Tension trusses are located under the space frame for overall stability of roof structure. Wind tunnel test had been conducted to evaluate accurate wind pressure for both structure and cladding design. LRB (lead rubber bearing) is located under the roof structure to reduce seismic force delivered from sub-structure.

Integrating multi-functional space and long-span structure in the early design stage of indoor sports arenas by using parametric modelling and multi-objective optimization

“…In fact, the height can be varied in a large range for different sizes of the buildings. For the Philippine Arena (50,000 fixed seats), which is the largest indoor arena in the world, the height for the last row is around 60 m [47].…”

“…Therefore, a complex load model is needed to define the wind and snow loads entirely according to design codes. Alternatively, considering the level of analysis typically used in architectural conceptual design, these loads can be simplified into fully and asymmetric vertical loads for the roof, [21,47]. The lateral load is usually resisted by other structural systems (e.g.…”
