“…The experimental studies carried out by the author of this paper involved full-scale testing of six independent telecommunication towers. The assumptions of the tests, the equipment used, and details on how the tests were conducted and how measurements were taken are provided in [28][29][30][31][32][33]. The reader is kindly asked to refer to these papers so that it is not necessary to repeat such details here.…”

The main goal of this paper is to provide recommendations for designing state‐of‐the‐art and lightweight steel lattice telecommunication towers which offer the highest possible load‐carrying capacity. The design rules presented in the paper are based on experimental results obtained for two independent tower structures. Full‐scale facilities, namely 42‐m‐high towers were tested. Stresses in compressed legs of lower segments of the towers, displacements of their tops, and, notably, failure mechanisms are analyzed. Technical solutions including additional equipment, such as service platforms and cable and access ladders, are also considered. Means of reinforcing tower structures with a focus on modifying buckling strength of legs and diagonal bracings are also discussed and justified.

“…In another study, structural reliability analysis was carried out on the effect of loads under wind load conditions, one of which was using structural analysis software such as SAP2000 (Gao and Wang 2018), Autodesk ROBOT Structural Analysis (Szafran, Juszczyk, and Kamiński 2020), ANSYS (Zheng and Fan 2018), experimental modeling with compressive load (Zhang and Xie 2018), experimental modeling of wind loads using the wind tunnel method (Zhang et al 2015). These methods can be simulated on the MStower software.…”

<p>Structural analysis has been widely applied in civil engineering. This analysis based on probability theory. Structural analysis was carried out to calculate the probability of failure and reliability of the structure. There are many cases of construction failure caused by uncertain environmental and human activities, including improper load in the external design process. In the process of designing a structure in Indonesia, complicated analysis is rarely carried out because of the complexity and impracticality of the analysis. Engineers and developers need to understand the behavior of the space truss structure and procedures in structural reliability analysis, Therefore it is necessary to simplify the structure in the analysis of the structure. This paper has carried out a structural reliability analysis using simple space truss modeling to understand its structural behavior and the principles of structural analysis under indeterministic load with simplified methods to make it more practical. A comparison of struktural analysis was carried out on 3 methods of structural analysis, manual calculation, ETABS v9.7.4, and MStower V6.20.1.11. The results of the three methods have the same value so that the structural analysis using MStower is reliable. In the loading approach, the load that is developed into a population of possible loads that can occur. Monte Carlo simulation is used by generate a sample of the load population that can represent the number of possible loads so as to reduce the number of analyzes. Random value generation methods were compared to get a more effective and practical method. The failure criteria are determined to obtain the limit state function of the structure so that the probability of failure and the reliability of the structure can be calculated. In this study, the limit state function was obtained in compression member with a 67% probability of failure and 33% reliability of the structure.</p>
