NUMERICAL SEISMIC FRAGILITY OF FIRE SPRINKLER PIPING SYSTEMS WITH THREADED JOINTS

02 Nov 2014 | Publications | Contributor(s): Siavash Soroushian, Manos Maragakis, Arash E. Zaghi, Alicia Echevarria, Yuan Tian, Andre Filiatrault

Abstract: Numerical modeling method was developed for fire sprinkler piping systems and used to generate seismic fragility parameters. The model accounts for inelastic response of threaded joints, braces, hangers, and wire restrainers. The model incorporates a nonlinear hinge model developed for...

Prediction of pressure coefficients on roofs of low buildings using artificial neural networks

26 Sep 2014 | Citations | Contributor(s): Y Chen, G.A Kopp, D Surry

This paper describes an artificial neural network (ANN) approach for the prediction of mean and root-mean-square (rms) pressure coefficients on the gable roofs of low buildings. The ANN models, which employ a backpropagation training algorithm, are capable of generalizing the complex, nonlinear...

Interpolation of pressure coefficients for low-rise buildings of different plan dimensions and roof slopes using artificial neural networks

26 Sep 2014 | Citations | Contributor(s): X. Gavalda, J. Ferrer-Gener, Gregory A. Kopp, Francesc Giralt

Database-assisted design (DAD) is emerging as an important tool to design buildings for wind effects. However, there is a need for robust interpolation methods for pressure coefficients to extend the range of conditions beyond those in the aerodynamic database from wind tunnel experiments. An...
