Evaluation of p-delta effect in structural seismic response

Abstract

Numerous recent studies have assessed the effect of P-Delta on the structures. This paper investigates the effect of P-Delta in seismic response of structures with different heights. For indicating the effect of P-Delta, nonlinear static analysis (pushover analysis) and nonlinear dynamic analysis (Time history analysis) were conducted by using finite element software. The results showing that the P-Delta has a significant impact on the structural behavior mainly on the peak amplitude of building when the height of the structures increased. In addition, comparison has been made between concrete and steel structure.

Capacitive studies of electrodeposited PEDOT-maleimide

“…12e). Eqn (8) was used to compute the coulomb efficiency. Only charging and discharging time is required in this equation because of the nearly ideal capacitive behaviors of PEDOT and PEDOT-maleimide.…”

“…6 This is because pseudocapacitors usually rely on fast faradaic redox reactions for charge storage, while double-layer capacitors adopt electrostatic interactions for charge accumulation. 5 Conductive polymers (CPs), such as polyaniline (PANI), 7 polypyrrole (PPy), 8 and poly(3,4-ethylenedioxythiophene) (PEDOT) 9 have been widely studied as electrode materials for pseudocapacitors. Compared with transition metal oxides such as RuO 2 and MnO 2 , CPs' advantages include their low toxicity, processability, and cost.…”

High Rise Buildings: Design, Analysis, and Safety

“…Since past decades, pushover or nonlinear static analysis has gained much interest within seismic engineering society [41]. However, utilizing this method for unsymmetrical-plan or high-rise buildings has a significant disadvantage since it is restricted to a single-mode response.…”
