摘要：
Double layered grid space structures are well known in the building industry for their ability to cover large areas. This paper presents the results of a parametric study on the various factors affecting the flexural behavior of double layered grid space structures, considering (i) various support arrangement (ii) concrete slab at the top and (iii) an experimental investigation on a full scale space grid. Based on the study it was concluded that top concrete slab enhances not only the strength of top chord compression members but also increase the strength and stiffness of the system with a fail safe system. It was found from the study that atleast 20% saving in steel is possible with a mid edge supported system.
