“…Two classes of approaches, the so-called material or micro-approaches and the geometrical or macro-approaches, are available (Li, 2018;Luo et al, 2019). The mainly used methods using discrete elements can be regarded, such as (The Constructor, 2019) ground structure approach (GSA) (Zhang et al, 2017;Shieh, 2994), solid isotropic material with penalisation (SIMP) method (Bensøe, 1989;Bendsoe and Sigmund, 2003;Sigmund and Maute, 2013, Grekavicius et al, 2016a& 2016b, Abdelwahab and Tsavdaridis, 2019, homogenisation-method (HM) (Bendsøe and Kikuchi, 1988;Groen and Sigmund, 2018), evolutionary structural optimisation (ESO) (Xie and Steven, 1993;Jiang and Jia, 2006), and level-set method (LSM) (Jiang and Jia, 2006). On the other hand, the mainly used meshless methods are element-free Galerkin (EFG) (Luo et al, 2013), moving particle (Liu et al, 1995), and peridynamics (Kefal et al, 2019).…”

With increasing demand of infrastructure to support power transmission and telecommunication systems, the need of erecting more towers has also been rising significantly. For many years, these towers were designed by using a conservative approach and the opportunities lying in the design optimisation of the towers were not leveraged. This paper presents the application of structural topology optimisation to lattice self-supported telecommunication towers in developing an improved solution in terms of weight-to-stiffness ratio. 2D and 3D topology optimisation studies were performed with highly optimised bracing systems reducing the amount of steel material used, thus its carbon footprint. The new exoskeleton structure is representing a lattice tower composed of 'high-waisted' bracing type and elliptical hollow sections (EHS). Comparative modal analyses demonstrated the structural performance of the optimised tower models. In addition, a research-led design was carried out for optimising the geometric cross-sectional properties of the optimised lattice tower subjected to quasi-static analysis followed by regression analysis. The cross-sectional parameters were progressively changed; explicitly the diameter and thickness of the members. The performance-based analysis and design of a topologically optimised lattice tower present alternatives to onerous approaches such as wind tunnel testing or finite element modelling. The results were further analysed to understand their viability in different loading design cases and the effect of cross-sections. Conclusions highlighted the benefits gained by introducing the structural topology optimisation process in the design of slender support structures.

Truss and Frames - Recent Advances and New Perspectives

Over the years, several optimization techniques were widely used to find the optimum shape and size of engineering structures (trusses, frames, etc.) under different constraints (stress, displacement, buckling instability, kinematic stability, and natural frequency). But, most of them require continuous data set where, on the other hand, topology optimization (TO) can handle also discrete ones. Topology optimization has also allowed radical changes in geometry which concludes better designs. So, many researchers have studied on topology optimization by developing/using different methodologies. This study aims to classify these studies considering used methods and present new emerging application areas. It is believed that researchers will easily find the related studies with their work.
