# Performance-Based Analysis of Single-Layer Cylindrical Steel Reticulated Shells in Fire
## 1 Introduction
[PERSON] [10] has established a model of steel portal frame buildings using the finite element program SAFIR, which is based on New Zealand's Design Code. [PERSON] [11] has carried out a fire safety analysis of three-dimensional (3D) frame structures such as industrial halls using a full-scale fire test. The results of the predicted mechanical response were analyzed to ensure the model was applicable to daily design practice. [PERSON] [12] has conducted a large number of case analyses on the high-temperature behaviors of large exhibition centers. Some suggestions have been made for the fire resistance design of steel truss structures. [PERSON] [13] has carried out an advanced analysis on fire in a long-span arch frame using a performance-based fire resistance design method, considering different fire locations, spans, and possibilities for fire spread. [PERSON] [14] has suggested objective requirements, including that the bearing capacity of the structure on fire be greater than the external load, that the deformation of the structure be less than the allowable deformation, and that the permanent damage caused by fire be minimized. [PERSON] and [PERSON] have written about performance-based design requirements of structural steel for fire conditions [15]. They provided structural engineers a method that will facilitate the design of structural steel for fire conditions using a performance-based approach. The method has been proposed that allows the designer to predict the time-temperature relationship expected in a compartment fire with a reasonable level of conservatism, which can be used to determine the required level of protection. However, most previous studies on the fire resistance performance of large structures have focused on steel frame structures and truss structures. There is little research on the fire resistance performance of reticulated shells. From the authors' knowledge, the researches on the fire performance of large span reticulated shell structures under real fire scenarios are still very limited and further researches are needed. This paper presents comprehensive case analyses on the fire resistance performance of single-layer cylindrical reticulated shells. Nonuniform fire temperature fields of single-layer cylindrical reticulated shells in different fire scenarios were generated using a Fire Dynamics Simulator (version 5, Baltimore, MD, USA). The influences of different parameters of the air temperature fields during fire--and how they affected the reticulated shell structure--were analyzed. Calculate the temperatures of the structural members within the large-space reticulated shell structure based on the local fire temperature fields. A finite element (FE) model was developed based on the studies [16; 17; 18; 19] by using the FEsoftware ABAQUS to model the structural behavior of single-layer cylindrical reticulated shells in different fire scenarios. The effects of various parameters on the responses of single-layer cylindrical reticulated shells during a fire were investigated. Using the results of the performance-based analyses in this research, we were able to create some guidance for the fire resistance design of single-layer cylindrical reticulated shells.
