“…The implementation of parapets around a roof perimeter and clogging of the drainage system are the main reasons that cause the accumulation of rainwater and snow, respectively. To reveal the collapse behavior of space truss roofs due to ponding, substantial investigations were performed by Biegus and Rykaluk [3], Piroglu et al [4], Piroglu and Ozakgul [5]. Inadequacy of standards and misestimating of Rosen and Schmit [6] investigated the effects of member imperfections and system imperfection on the behavior of structural system.…”

The aim of this paper is to investigate the nonlinear behavior of space truss roofs subject to different load accumulation forms considering the effect of initial imperfection and slenderness ratio of the truss members. For this, a typical space truss roof using MERO-connection type with flat double-layer was selected as a sample. 3D model of the roof was developed and analyzed by using OpenSEES. Nonlinear behavior of each typical bar of the space truss roof, which, was mainly composed of particular sub-elements such as a tubular element, bolts, sleeves and spheres was represented by a single truss bar. Axial load-displacement relationship of each single truss bar was obtained from nonlinear analysis performed under reversal cyclic loading. Besides, three different types of load distribution that simulates accumulation of rainwater or drifted snow were taken into account as an external load acting on upper layer of the roof system. Analyses results showed that load carrying capacity of the space truss roofs was susceptible to the form of accumulation and reduces abnormally when the accumulation, in particular, occurred locally. Furthermore, failure mode of the system designed with optimal solution was dominated by buckled truss bars and brittle failure occurred. Also initial imperfection had a negative effect on the members in compression. Bu çalışmada uzay kafes çatı sistemlerinin çeşitli yük birikme senaryoları altındaki doğrusal olmayan davranışı, çubuk eleman başlangıç kusurları ve çubuk eleman narinlikleri de dikkate alınarak incelenmiştir. MERO düğüm noktasına sahip iki adet örnek uzay kafes çatı sistemi OpenSEES yazılımı üç boyutlu olarak modellenerek analizler gerçekleştirilmiştir. Bulonlar, somunlar ve düğüm noktası kürelerinden oluşan her bir çubuk elemanın davranışı tekil çubuklar üzerinde tanımlanarak genel sisteme aktarılmıştır. Her bir çubuk elemanın eksenel yük-yerdeğiştirme davranışları çevrimsel tekrarlı yükler altında analizler gerçekleştirilerek elde edilmiştir. Genel sistem analizleri çatının tamamında, yarısında ve dörtte birinde yağmur suyu veya kar yükü yığılmalarını yansıtacak şekilde belirlenen yükleme altında gerçekleştirilmiştir. Analizler sonucunda uzay kafes çatı sistemlerinin yük yığılmalarına karşı hassas oldukları ve lokal bölgelerde oluşan yük yığılmalarının sistemin taşıma kapasitesini düşürdüğü görülmüştür. Bunun yanında, en ekonomik kesitlerle boyutlandırılan sistemde göçme basınç çubuklarının burkulması ile gevrek bir şekilde meydana gelmiştir. Ayrıca, çalışma kapsamında başlangıç kusurlarının çubuk elemanların basınç kapasitelerini düşürdüğü görülmüştür.

“…Since the collapse of the Romexpo Pavilion in Bucharest, Romania ( which was comprised of a singlelayer spherical reticulated shell with a span of 93.5 m and rise of 19.1 m) in 1961 and the destruction of the Hartford Civic Centre ( which was comprised of a space truss structure with a span of 110 m) in 1978, the traditional concept that the progressive collapse of a spatial grid structure following the loss of one important member can be prevented by a large degree of redundancy has been changing [3,4]. Cases about the progressive collapse of long-span spatial grid structures have been reported more frequently than ever because of the widespread use of such structures in public buildings, which has enhanced socioeconomic development [5,6,7].…”

Method for Evaluating the Progressive Collapse Resistance of Long-Span Single-Layer Spatial Grid Structures

In recent years, researchers have increasingly reported the progressive collapse of long-span spatial grid structures. However, research on long-span spatial grid structures, especially single-layer spatial grid structures, remains limited. Thus, this study conducted an incremental dynamic analysis to develop a suitable method for evaluating single-layer spatial grid structures. The method uses a quantitative evaluation index called the collapse margin ratio. Engineering cases were analysed to validate the proposed method. For instance, the proposed method was used to evaluate the progressive collapse of the main stadium of the Shenzhen Universiade Sports Centre. The results showed that the roof of the structure has good resistance against progressive collapse from the perspective of quantitative analysis, even though the cantilever length reached 51.9-68.4 m at some locations, and the novel method is not restricted by the structural form. Thus, the method can be used to quantitatively evaluate a structure's resistance to collapse.

“…Meløysund et al (2007) indicate that drifting occurs even for light winds (0.3-1.5 m/s), but wind velocities greater than 3.4 m/s will induce the snow to move considerably faster horizontally than vertically, thus producing a significant redistribution of snow. Biegus and Rykaluk (2009) found that the reason for the collapse of a steel building in Katowice was the localized overloads associated with drifted snow. Snow overloads of more than twice the snow load defined in the Polish standard were measured in some localized areas of the roof.…”

Large diameter steel silos usually require a beam structure to support rooftop inspection gangways and resist loads derived from the snow and wind actions. The existence of localized overloads caused by drifted snow on roofs as a consequence of the wind action has been reported in the literature. European standard EN 1991-1-3 also considers the need of taking into account asymmetric patterns for snow loads calculation. However, conical roofs are not included in the specific list of cases considered by this standard. The present work compares the normal stresses and displacements produced in a conical steel silo roof structure by applying balanced loads distributed on the whole roof and unbalanced loads applied on a roof sector. Experimental measurements and a three-dimensional beam model developed by the authors have been used to predict the stresses and vertical displacements of a metal silo roof structure measuring 18.34 m in diameter. The results show that the existence of an asymmetric load pattern produces higher normal stresses (up to 23%) and vertical displacements (up to 50%) than those derived from balanced loads, for any similar load per beam considered.
