Abstract: Experimental observations on 11 RC columns tested at Nanyang Technological University and existing experimental data of 79 shear-critical RC columns are presented. Significant arch action is found in columns with a small ...

Abstract: This paper seeks to examine the concrete contribution to shear strength and determine the inclination of the compressive strut within the variable truss model for slender RC shear-critical beams with stirrups. Using the ...

Abstract: Excessive deflections unexpected at the midspan have commonly appeared in long-span prestressed concrete box girder bridges, mainly because of the high degree of uncertainty in concrete creep and shrinkage, prestress loss, ...

Abstract: The long-term behavior of long-span prestressed concrete continuous rigid-frame bridges is significantly sensitive to creep and shrinkage. Therefore, it is important to accurately estimate creep and shrinkage effects. This ...

Abstract: Adjacent precast, prestressed multibeam bridges have often been used for medium- and short-span bridges. However, there have been longitudinal cracking problems in shear keys and overlays commonly seen on some adjacent ...

Abstract: An experimental investigation has been conducted to examine the seismic behavior of seven shear-critical, high-strength concrete columns and one normal-strength concrete column. The effects of compressive strength of ...

Abstract: AbstractAccurately predicting the ultimate shear strength of RC beams, especially those with intermediate shear spans, presents a significant challenge. This complexity arises from the intricate interplay of flexural and ...
