Analysis of Thermal Environmental Effects on Precast, Prestressed Concrete Bridge Girders: Temperature Differentials and Thermal Deformations
Lee, Jong-Han; Kalkan, Ilker (Multi-Science Publ Co Ltd, 2012)AASHTO specifications provide vertical thermal gradients for the thermal design of precast, prestressed concrete bridge girders. However, the thermal behavior of the girders pertains to not only vertical thermal movement ... -
Effect of shrinkage restraint on deflections of reinforced self-compacting concrete beams
Kalkan, Ilker; Lee, Jong-Han (Korean Society Of Civil Engineers-Ksce, 2013)This paper presents the results of a study aimed at investigating the effects of restrained shrinkage on the in-plane deflection behavior of reinforced beams cast with self-compacting concrete. The load-deflection data ... -
Experimental and Analytical Investigation of Lateral-Torsional Buckling of RC Beams with Geometric Imperfections
Lee, Jong-Han; Kalkan, Ilker (Trans Tech Publications Ltd, 2014)The design of reinforced concrete beams has usually focused on the ultimate flexural capacity and disregarded the lateral stability of the beams. However, the development of high-strength concrete and the implementation ... -
Rollover instability of precast girders subjected to wind load
Lee, Jong-Han; Kalkan, Ilker; Lee, Jong-Jae; Cheung, Jin-Hwan (Ice Publishing, 2017)The use of longer and deeper precast concrete girders has created concern regarding their rollover instability, particularly during construction. Current design and construction specifications do not provide any specific ... -
Seismic performance of R/C structures under vertical ground motion
Bas, Selcuk; Lee, Jong-Han; Sevinc, Mukadder; Kalkan, Ilker (Techno-Press, 2017)The effects of the vertical component of a ground motion on the earthquake performances of semi-ductile high-rise R/C structures were investigated in the present study. Linear and non-linear time-history analyses were ...
