CELL4 is a program based upon the finite element method and is particularly suited for the analysis of post-tensioned box girder bridges of constant depth which have arbitrary plan geometry and support conditions. The bridge can be straight, curved, or quadrilateral in plan. The longitudinal interior webs must be vertical, but the longitudinal exterior webs can be vertical, sloping, or curved. Transverse diaphragms can be modelled by vertical web elements or by special web elements in regions with sloping or curved webs. The top and bottom deck slabs as well as the interior and the exterior webs may be prestressed. Boundary conditions at any nodal point are arbitrary, allowing rigid supports as well as translational and rotational elastic supports, oriented in any arbitrary direction to simulate the stiffness of the supporting columns and bents. For prestressing analysis an automatic input has been provided to define the geometry of the two types of post-tensioned unbonded tendons which can be used. Each panel or slab tendon can be stressed either from one end or both ends, and losses due to friction and anchorage slip are accounted for. In order to facilitate the interpretation of output, an automatic integration of internal forces to give individual girder and total sectional force resultants is incorporated. This permits a better understanding of the load carrying mechanism in a complex bridge system, and can also be used to carry out equilibrium checks easily.**Conspan**- Analysis and design of simple-span and multi-span precast and prestressed bridge beams.**LAPBOX**- Legacy software from 1986 for the analysis of curved nonprismatic reinforced and prestressed concrete box girder bridges.

LAPBOX is an implementation of a numerical procedure for the analysis of curved nonprismatic reinforced and prestressed concrete box girder bridges. Thin-walled beam theory and the finite element method are combined to develop a curved nonprismatic thin-walled box beam element. The cross section of the element is a rectangular single-cell box with side cantilevers. The axis of the element is curved in plan. The cross sectional dimensions vary along the element axis. Eight displacement degrees of freedom, including transverse distortion and longitudinal warping of the cross section are considered at each of the three element nodes. Small displacements and small strains are assumed in the element formulation. Prestressing, consisting of post-tensioned bonded tendons in the longitudinal direction, is considered. The tendons are idealized as straight prestressing steel segments between nodes of the box beam elements. Friction and anchorage slip losses are considered.**PGSuper**- Precast-Prestressed Girder design and analysis software.**PSBeam**- Design of precast, prestressed concrete bridge girdes.**SAM Integrated Bridge Design Software**- Specialized bridge design software for medium span bridges that integrates code checking with analysis.
