Book Description
This report establishes a user's manual for the acceptance, repair, or rejection of precast/prestressed concrete girders with longitudinal web cracking. The report also proposes revisions to the AASHTO LRFD Bridge Design Specifications and provides recommendations to develop improved crack control reinforcement details for use in new girders. The material in this report will be of immediate interest to bridge engineers.

Standardized Longitudinal Connection Detail for Decked Precast Prestressed Concrete Girders
Author: Ramzi Muftah Ali Abduallah
Publisher:
ISBN:
Category : Civil engineering
Languages : en
Pages : 99
Book Description
The use of decked precast prestressed concrete girders is becoming popular in accelerated bridge construction. DPPCGs are assembled and connected on site using grout or concrete longitudinal connections. The durability performance of these connections is a concern. The objective of this research is to document the longitudinal connection behavior with respect to its design parameters, and establish a process for developing a standardized connection detail considering the demands due to live load and temperature gradient load. In order to demonstrate this process, decked bulb tee and decked box beam girders were considered. Finite element models, under various types and levels of loads and in conjunction with the design parameters, were used for evaluating the internal forces at connections. Structural analysis reveals that the TG load is significant and needs to be considered in connection design, and moment at connections increases when slab thickness increases, bridge materials have greater strength and thermal properties, and diaphragms have larger sections and smaller spacing. Structural design shows that due to the TG moment, crack control criteria at service limit state governs the flexural design, and tensile stress in steel in AASHTO (2012) eq. 5.7.3.4-1 should have an upper limit to prevent steel from yielding.
