MASH TL-4 Engineering Analyses and Detailing of 36-inch and 42-inch High Median Barriers for LADOTD
| 项目名称： | MASH TL-4 Engineering Analyses and Detailing of 36-inch and 42-inch High Median Barriers for LADOTD |
| 摘要： | The research objective is to analyze the strengths of the four proposed retrofit designs considered for this project in accordance with AASHTO LRFD Section 13 Specifications for MASH Test Level 4 impact conditions. These designs are briefly described as follows: 1. 36” single slope median barrier without the longitudinal open joint (as shown in Figure 1 except no longitudinal open joint). 2. 36” single slope median barrier with longitudinal open joints (as shown in Figure 1). 3. 42: single slope median barrier without the longitudinal open joint (same as Figure 1 except 42” tall and 8” wide at top). 4. 42” single slope median barrier with longitudinal open joint (same as 2 except 42” tall, 8” wide at top). Recommendation(s) and improvement(s) will be made as necessary based on our analyses to improve the strength and performance of MASH TL-4 conditions. |
