Individuals, Chief Research Engineer | Seoul, South Korea

About

Taehun Ha is Chief Research Engineer at Architectural Engineering Research Team of Daewoo E&C, Seoul, South Korea. He received his BS, MS, and Ph.D. from the Department of Architecture, Seoul National University, Seoul, South Korea in 1997, 1999, and 2004, respectively. Since he joined Daewoo E&C, he carried out many types of research on the long-termed movement of high-rise buildings and developed in-house software for construction stage analysis. The software has been used in more than thirty actual high-rise projects to predict their movements and take corrective measures during construction

Prediction of Time-dependent Lateral Movement Induced by Differential Shortening in Tall Buildings

Taehun Ha & Sungho Lee, Daewoo E&C; Sangdae Kim, Korea University

High-rise buildings move during construction due to time-dependent material properties of concrete (creep and shrinkage), construction sequences, and structural shapes. The building movements, including vertical...

A Software Tool for the Analysis of Time-Dependent Effects in High-Rise Buildings

Carlo Casalegno, IUAV University of Venice; Mario Alberto Chiorino, Politecnico di Torino; Taehun Ha & Sungho Lee, Daewoo Engineering and Construction

Increased use of concrete in high-rise buildings has made these structures especially sensitive to delayed deformations due to concrete’s natural tendency to creep and shrink....

Case Study of Structural Cracks in Irregular RC Tall Building During Construction

Dr. Taehun Ha & Sungho Lee, Daewoo E&C

Structural cracks happen during construction of RC buildings due to various reasons but they are more often considered as construction faults rather than being considered...
