Abstract: Yellow River Estuary Model Hall is a hydrodynamic model building. Hybrid structures composed of truss strings and reticulated shell with the span of 148 meters is adopted, which meets the demand of building function and appearance. Key technologies were presented, such as the selection of structure type, control of tension stress, treatment of special supports, analysis of design-construction integration, wind-resistant design, elastic-plastic design under rare earthquake and continuous collapse prevention design. Three-dimensional model of the large span structure was established with the Rhinoceros software in design. Wind tunnel test and wind-induced vibration analysis were carried out. Structural responses under three-dimensional seismic action, gravity load, snow load, equivalent wind load and temperature effect were analyzed. The results verify the reliability, security and rationality of the structure.

Keywords: large span structure; hybrid structure composed of truss string and reticulated shell; design-construction integration
