Starrucca Viaduct
The Starrucca Viaduct is a stone masonry railroad viaduct completed in 1848 for the New York and Erie Railroad at Lanesboro, Pennsylvania, and still carrying freight today.
Starved Rock Lock and Dam
Starved Rock Lock and Dam is a lock and gated dam on the Illinois River near Utica, Illinois, opened in 1933 as part of the Illinois Waterway.
State Hydraulic Works (Turkey)
State Hydraulic Works (Devlet Su İşleri, DSİ) is the Turkish state agency managing water resources, headquartered in Ankara and established in 1953, best known for building dams.
Statically determinate structure
A statically determinate structure is a structure whose support reactions and internal forces can be calculated from the equations of static equilibrium alone, without information about material stiffness or deformation.
Stay cable
A stay cable is a tensioned steel member running directly from a bridge tower to the deck, the defining element of cable-stayed bridges since Sweden's Strömsund Bridge of 1955.
Stay cable systems
A stay cable system is the complete engineered product that carries a cable-stayed or extradosed bridge deck in tension from deck to pylon, including strands, anchorages, and dampers.
Stay-cable maintenance and monitoring
Stay-cable maintenance and monitoring is the inspection, condition assessment, and replacement of stay cables on cable-stayed bridges, where corrosion hidden inside anchorages threatens service life.
Steel dam
A steel dam is a fixed wall built as a steel deck supported by inclined steel struts. Only three were constructed in the United States between 1897 and 1910.
Steel Pier (Atlantic City)
Steel Pier is an amusement pier on the Boardwalk in Atlantic City, New Jersey, opened in 1898 and once billed as the Showplace of the Nation.
Stepped spillway
A stepped spillway is a dam spillway whose chute is built as a series of steps that dissipate flowing water's energy before it reaches the downstream channel.
Stepwell
A stepwell, also called a baoli or bawdi, is a well or pond reached by a descending staircase, giving year-round access to groundwater in India.
Stickney Water Reclamation Plant
The Stickney Water Reclamation Plant in Cicero, Illinois, near Chicago, is widely considered the world's largest wastewater treatment plant, cleaning about 700 million gallons of wastewater daily since 1930.
Stilling basin
A stilling basin is a concrete pool at the toe of a spillway that forces a hydraulic jump to slow fast release flow, protecting the riverbed from scour.
Stockholm water supply
Stockholm water supply delivers drinking water from Lake Mälaren to about 2 million people, treated at the Norsborg and Lovö waterworks and distributed through some 2,200 km of pipes.
Stone Arch Bridge (Minneapolis)
The Stone Arch Bridge is a 2,100-foot stone railroad bridge with 23 arches crossing the Mississippi River in Minneapolis, built for James J. Hill between 1881 and 1883.
Stonecutters Bridge
Stonecutters Bridge is a cable-stayed road bridge in Hong Kong carrying Route 8 across the Rambler Channel between Stonecutters Island and Tsing Yi, opened in December 2009.
Storm drain
A storm drain, also called a storm sewer, is an engineered system that collects street runoff through grated inlets and carries it by pipes to streams, usually untreated.
Storm Water Management Model
The Storm Water Management Model (SWMM) is an open source EPA program that simulates the hydrology, hydraulics, and water quality of urban runoff and drainage systems worldwide.
Stormwater
Stormwater is rain and snowmelt that flows over impervious surfaces such as paved streets and rooftops instead of soaking into the ground, picking up pollutants and stressing urban streams.
Stormwater best management practice
A stormwater best management practice (BMP) is a structure or procedure that reduces the volume, rate, or pollutant load of runoff, through facilities like detention ponds and source controls.
Story Bridge
The Story Bridge, Brisbane's steel cantilever bridge across the Brisbane River, links Kangaroo Point with Fortitude Valley; opened in 1940, it remains Australia's longest cantilever bridge.
Strait of Gibraltar crossing
The Strait of Gibraltar crossing, also known as the Gibraltar bridge, is a proposed rail tunnel linking Spain and Morocco, planned at about 42 km long.
Strait of Messina Bridge
The Strait of Messina Bridge is a planned suspension bridge linking Messina in Sicily with Calabria, designed to carry the world's longest suspension span at 3,300 meters.
Street
A street is a public way in a town or city that provides space for movement and serves as the setting for buildings, commerce, and public life.
Stressed ribbon bridge
The stressed ribbon bridge, or catenary bridge, is a tension structure like a suspension bridge with the cables embedded in a thin deck following a catenary arc.
Strong column-weak beam
Strong column-weak beam is a seismic design principle requiring columns to be stronger than the beams at a joint, so beams yield first in earthquakes.
Structural and Multidisciplinary Optimization
Structural and Multidisciplinary Optimization is a peer-reviewed Springer engineering journal founded in 1989 as Structural Optimization; it covers structural, fluid, thermal, and electromagnetic optimization and is ISSMO's official journal.
Structural Engineering International
Structural Engineering International (SEI) is a quarterly peer-reviewed journal covering structural engineering, founded in 1991 to bridge professional practice and academic research, published by Taylor & Francis for IABSE.
Structural health monitoring
Structural health monitoring, known for bridges as bridge health monitoring, uses sensor networks to detect, locate, and quantify damage in structures such as bridges and buildings.
Structural integrity and failure
Structural integrity and failure covers how structures such as buildings, bridges, and dams carry their intended loads, absorb local damage, and fail when that ability is lost.
