Examining the effects of different seismic base isolators on the seismic behavior of a real-size steel truss structure

Serdar Çarbaş, Refik Burak Taymuş, Mehmet Özdemir

Challenge Journal of Structural Mechanics (2025) 11(2) 106-115

In this study, the seismic behavior of a real-size steel truss structure is examined for elastomeric isolator, double friction pendulum isolator, and fixed support conditions. Hence, the main aim of the study is to examine which type of support is safer for se...
Nonlinear in-plane response of 3D-printed concrete walls with varied infill patterns: Experimental mix design and numerical structural assessment

İsmail Hakkı Tarhan, Yeşim Tarhan

Challenge Journal of Structural Mechanics (2025) 11(3) 160-173

This study investigates the nonlinear in-plane structural behavior of 3D-printed concrete wall elements with two representative internal infill patterns ‒ lattice (L) and triangular (T) ‒ using finite element modeling informed by experimentally derived materia...
Metaheuristic approaches for optimum design of cantilever reinforced concrete retaining walls

Gebrail Bekdaş, Rasim Temür

Challenge Journal of Structural Mechanics (2017) 3(1) 23-30

An approach is presented for optimum design of cantilever reinforced concrete (RC) retaining wall via teaching-learning based optimization (TLBO) algorithm. The objective function of the optimization is to minimize total material cost including concrete and re...
Optimal metaheuristic design of CFRP wrapping for enhancing the shear capacity of reinforced concrete columns

Ammar Khalbous, Gebrail Bekdaş, Sinan Melih Nigdeli, Aylin Ece Kayabekir

Challenge Journal of Structural Mechanics (2026) 12(1) 55-64

Reinforced concrete (RC) columns are prone to brittle shear failure under lateral loads like earthquakes, especially in older structures. Carbon fiber reinforced polymer (CFRP) wrapping effectively enhances shear capacity, ductility, and energy dissipation. Th...
A different approach for green concrete production: Determination of the effect of e-waste and waste rubber powder on durability properties of concrete

H. Alperen Bulut

Challenge Journal of Concrete Research Letters (2024) 15(3) 69-81

This study was carried out to present a different approach to green concrete production by utilizing electronic waste (e-waste) and waste rubber powders in order to provide a solution to both the cost and carbon footprint problems arising from the rapid consum...
