Instead, they are typically supported by pre-embedded corbels in the pier columns. This method requires pre-embedded steel plates and rebar, which is complex and difficult to implement. Direct support with steel rods has limited load-bearing capacity and weak bending resistance, making it unsuitable for heavy superstructures. Therefore, a composite steel rod and section steel structure was considered to increase load-bearing capacity, simplify the construction process, and improve efficiency. Utility Model Content
