Design of reinforcement for concrete co-planar shell structures using optimization techniques

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

simultaneous shape and reinforcement topology optimization of shell structures by using the method of moving asymptotes

this article is devoted to the simultaneous optimization of shape and topology of shell structures. the optimum shape is obtained together with the optimum layout for the reinforcement layers at the both sides of the shell surface. to solve this problem the finite element method is employed. it is assumed that each element is comprised of a porous media with microscopic rectangular voids where ...

FRP Shear Reinforcement for Concrete Structures

Considering the Soil Effects on Design Process of Performance-Based Plastic Design for Reinforced Concrete Structures

In this research, Performance-Based Plastic Design (PBPD) method has been modified according to the proposed method for considering Soil–Structure Interaction (SSI) effects. In the proposed modified method, based on the existing relationships and in order to maintain the simplicity of the PBPD design method, two important parameters have been modified in the PBPD design method. These two parame...

OPTIMAL DESIGN OF JACKET SUPPORTING STRUCTURES FOR OFFSHORE WIND TURBINES USING ENHANCED COLLIDING BODIES OPTIMIZATION ALGORITHM

Structural optimization of offshore wind turbine structures has become an important issue in the past years due to the noticeable developments in offshore wind industry. However, considering the offshore wind turbines’ size and environment, this task is outstandingly difficult. To overcome this barrier, in this paper, a metaheuristic algorithm called Enhanced Colliding Bodies Optimization...
