    slab detail in Chapter 4 of the NMDOT Bridge Procedures and Design Guide, hereinafter referred to as Design Guide. Girder analysis and design is performed using the computer program CONSPAN, Version Input data and design loads needed for the computer analysis are developed and listed. From the resulting output, a final girder. Multi-girder systems, girder-substringer systems, twin I-girders, U-girders for composite box girders, girders with orthotropic deck, and steel trusses are thoroughly discussed. The chapters on lateral flexure-torsion buckling and local instability have been deepened and include recent information from finite-element analysis.

Important time-dependent redistributions of stresses and internal forces throughout the bridge were also measured. The test results were compared with analytical predictions obtained by means of a numerical model developed for the nonlinear and time-dependent analysis of segmentally erected, reinforced and prestressed concrete structures.

    In the present thesis, a numerical technique is introduced and a computer program is developed for the time-dependent analysis of se,pentally erected curved,prestressed box-girder bridges and other structures. The program is capable of predicting the response.

A method is presented for the analysis of curved segmentally erected prestressed concrete box girder bridges including time-dependent effects. The segments can be either precast or cast-in-place.

The bridge cross section consists of a single box section with vertical or inclined webs and can have cantilever by: 7. MINIMIZING CONSTRUCTION PROBLEMS IN SEGMENTALLY PRECAST BOX GIRDER BRIDGES.

One of these examples was the three-span segmental bridge constructed in Corpus Christi, Texas, during The fourth report summarized the development of an incremental analysis procedure and computer program to analyze segmentally erected box girder bridges.

Six more bridges in various coun-tries were reviewed in another state-of-the-art paper published in ° In North America well over 50 box girder bridges of segmental construction have either been built or are under construction.

On medium spans, span-by-span construction of precast segmental bridges competes with balanced cantilever erection of constant-depth segments, incremental launching and in-place span-by-span. The results amount to a wake-up call: 56 other large-span, prestressed concrete, segmentally erected box girders (66 by the time of proof) have already been found to exhibit excessive long-time.

—PRECAST SEGMENTAL BOX GIRDERS (A) General Except as otherwise noted in this section, the provisions of Section 6— Prestressed Concrete shall apply to the analysis and design of precast segmental box girder bridges. Deck slabs without transverse post-ten-sioning shall be designed under the applicable provisions of Section 5.

When the deck is not cable-stayed, balanced cantilever bridges typically have box section. The deck may have constant or varying depth. Varying-depth precast segmental box girders have been used on m spans and are mostly competitive on m spans.
