摘要
Abstract
In order to study the stress performance of a new type of prefabricated guardrail,this paper takes the prefabricated guardrail of a certain highway in Guangxi as an example,and uses LS-DYNA finite element software to consider the longitudinal and transverse components of passenger collision velocity.The mechanical performance analysis is carried out.The final calculation results show that the prefabricated guardrail with steel bar vertical splicing scheme has good protective ability and stress performance.The design scheme of the prefabricated steel bar vertical splicing connection guardrail not only effectively shortens the construction period of traditional cast-in-place beams,improves construction safety,but also significantly reduces construction costs.关键词
