Efficient Rebar Layout Estimation Enabled by a Custom Detection Network and Enhanced Visual Measurement

Fangzhou Lin, Yuyao Cheng, Jian Zhang

Abstract Accurate detection of reserved rebar spacing in precast concrete structures is essential for ensuring proper component assembly and structural safety. However, conventional measurement methods are inefficient, error-prone, and involve potential safety risks. To address these issues, this paper investigates high-precision rebar …

Deflection Prediction of Track‐Slab Construction of High‐Speed Railway Bridge Based on Impact Vibration Testing and Flexibility Identification

Ze Chen, Siqi Jia, Qi Xia, Jian Zhang

Line shape control is the most critical step in the construction of high‐speed railway bridges. The deflection of long‐span bridges (such as cable‐stayed bridges) is more complex as a multipoint elastic‐supported system, especially during track slab construction. Accurately predicting the line shape …
