Numerical Simulation of Steel Bolted Beam-column Connections Subjected to Dynamic Loading Liu Chang1,a, Tan Kang Hai2,b, Fung Tat Ching3,c, Andrew Tyas4,d 1,2,3School of Civil & Environmental Engineering, Nanyang Technological University, Singapore 4Department of Civil & Structural Engineering, University of Sheffield, Sheffield, UK aliuc0014@ntu.edu.sg; bckhtan@ntu.edu.sg; cctcfung@ntu.edu.sg; da.tyas@sheffield.ac.uk Keywords: finite element simulation; steel bolted beam-column connections; dynamic loading; failure criterion Abstract: This study presents the development of a finite element model with the capability to simulate and analyse the response of steel bolted beam-column connections subjected to rapid rate of applied loading.
INTRODUCTION Progressive collapse is one of the most attractive research areas in structural engineering, as it holds the key to the survival of a structure after a blast event.
Therefore, a dynamic increase factor (DIF) of 1.1 developed by Department of the US Army Corps of Engineers [6] was taken into account for the strain-rate effects of bolts and welds when connections subjected to ultra-fast rate of loading.

Natural frequencies and mode shapes of laminated composite skew hypar shells with complicated boundary conditions using finite element method Ajay Kumar1, a, Pradeep Bhargava2, b and Anupam Chakrabarti3, c 1Research Scholar, Department of Civil Engineering, IIT Roorkee, INDIA 2Professor, Department of Civil Engineering, IIT Roorkee, INDIA 3AssociateProfessor, Department of Civil Engineering, IIT Roorkee, INDIA asajaydce@gmail.com, bbhpdfce@iitr.ernet.in, canupam1965@yahoo.co.uk Keywords: composite, skew, hypar shells, free vibration, higher order theory, finite element method, boundary conditions Abstract In the present investigation, free vibration behaviour is studied for the laminated composite skew hypar shells having twist radius of curvature.
New results are presented by varying geometry, boundary conditions, ply orientations and skew angles which will serve as benchmark for future researchers. 1 Introduction Laminated composite shell structures characterized by high strength to weight ratio are used in different weight sensitive engineering structures.
Among the different shell configurations, the aesthetically appealing hyperbolic paraboloid shell bounded by straight edges commonly known as the hypar shell is very popular in engineering application.
As such the present model may be recommended for wide applications to solve many engineering problems related to vibration of composites skew hypar shells.
