In structural mechanics, traditional analyses methods usually employ matrix operations for obtaining displacement and internal forces of the structure under the external effects, such as distributed loads, earthquake or wind excitations, and temperature changing inter alia. These matrices are derived from the well-known principle of mechanics calle...

On August 11, 2021, one of the most destructive flood disasters occurred in the Western Black Sea Basin of Turkey. The flood resulted in the death of 76 individuals, with an estimated 30,000 people being affected by the disaster. A maximum precipitation depth of 400 mm/day was recorded at one station, indicating that the flood occurred at least dur...

The stable equilibrium state of a structural system corresponds to the relative minimum total potential energy state. In order to analyze the structures by energy principle, energy minimization is addressed as an optimization problem. In early studies, few structural problems are investigated with the aid of energy minimization; flat and curved pla...

Seismic isolation systems exposed to far-fault earthquakes can reduce floor accelerations and story drift ratios to acceptable levels. However, they exhibit different structural performances in each earthquake due to different excitation frequency contents. By optimizing the isolation system parameters, their performance may be maintained at the be...

Urbanization of a watershed affects both surface water and groundwater resources. When impervious area increases, the excess runoff and volume of water collected at the downstream end of the watershed also increases, due to the decrease in groundwater recharge, depression storage, infiltration and evapotranspiration. Low-impact development (LID) me...

Construction of foundations on soft/loose soil deposits causes some big problems in geotechnical engineering. The vertical loads can cause failure and/or extreme settlement in soft/loose soil deposit. Constructing piles under foundations to transfer the loads to stiff soil layer is one of the widely used solutions to prevent these problems. The int...

Minimum potential energy principle is the basis of the most of the well-known traditional techniques used in the structural analysis. This principle determines the equilibrium conditions of systems with reference to minimization of the sum of the total potential energy of the structure. In traditional applications, this methodology is formulized by...

Internal forces and displacement caused from the thermal effects can be important for structures that can be subject to large temperature changes. For that reason, determining these effects accurately during the design process is essential for security of structural systems. In this paper, a methodology called total potential optimization using met...

The optimum design of reinforced concrete (RC) structures with the minimum weight is not an easy task due to concrete and steel reinforcement bars have extremely different mechanical behavior, i.e. compressive strength, tensile strength, and material cost. Thus, the optimum design of RC structures may not be provided by the conventional approaches....

According to the well-known principle of mechanics named minimum potential energy, if the total potential energy of a system is minimum, the system is in equilibrium state. Conventional methods use mathematical operations to find minimum potential energy of structures. Alternatively, metaheuristic algorithms that are frequently used for minimizatio...

Determination of nonunique configurations of structures is a problem which cannot be treated readily using classical methods of analysis. In the literature, these kinds of problems are tackled for some simple problems, like trusses with a small number of joints and members, and with specially designed approaches. The recent method of analysis calle...

The nonlinear behavior of the structure is an important subject that must be taken into consideration during the structural design. This behavior can occur due to large deformations and/or material nonlinearity. Elasto-plastic behavior is a well-known idealization that makes the structure highly nonlinear. By using the method of Total Potential Opt...

Cable and tensegrity structures give an ability to create new structural forms in the architectural designs which are light and flexible. Since their flexibility allows large structural displacements, a geometrically nonlinear solution method has to be used during the analysis of this type of structures. A further reason for adopting a nonlinear me...
