Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA It is rare nowadays that a whole year goes by without a major earthquake event wreaking havoc somewhere around the world. In some cases, like the 2005 Banda Ache earthquake in Indonesia, the damage involved large geographic areas and casualties in the six figures. In general, the number and intensity of earthquakes is not increasing, however, the vulnerability of the built environment is...

We recently proposed a method that allows dichoptic visual stimulus presentation and binocular eye tracking simultaneously1. The key is the combination of an infrared eye tracker and the corresponding infrared-transparent mirrors. This manuscript provides an in depth protocol for initial setup and everyday operation.

This video demonstrates the development of a 3D neuronal culture coupled to a planar microelectrode array with hippocampal neurons. The isolated neurons form a 2D network on the microelectrode array's active area and adhere to glass microbeads in a multi-well plate with a membrane insert. Upon transferring these neuron-coated microbeads to the electrode, they organize into an interconnected 3D neural network.

We demonstrate the utility of nest building behavior in laboratory mice as an indicator of welfare. Nest scoring is a sensitive technique that is altered by temperature, illness, and aggression. The time to integrate into nest test (TINT) is a simple cage-side assessment that can detect postoperative pain.
FAQs
Engineers trace each applied force through the structural system to the ground, examining how slabs, beams, columns, walls, and foundations share the demand. This load path matters because a weakness or discontinuity in one element can affect overall stability. Reviewing the complete sequence helps connect element sizing with safe structural performance.
Strength, stiffness, and stability describe different performance requirements. Strength concerns whether an element can resist applied stress without failure; stiffness concerns how much it deforms; stability concerns whether its configuration remains controlled under load. Considering all three prevents a design from appearing adequate by one measure while remaining vulnerable through another.
Gravity, wind, seismic forces, and other applied stresses do not challenge a building in the same way. Engineers therefore examine the relevant force effects when selecting structural elements, materials, and dimensions. This comparison supports designs that remain safe across expected conditions rather than those optimized only for ordinary gravity loading.
Material selection and member dimensions work together rather than as separate decisions. Engineers use them to satisfy strength, stiffness, and stability requirements while also considering durability and efficiency. Construction methods and architectural demands can influence these choices, so the final structural arrangement reflects both analytical performance and how the building will be realized.
A typical design process begins by identifying the building’s spatial and architectural requirements, then considering loads, structural elements, materials, dimensions, and foundation support. Engineers analyze equilibrium, strength, stiffness, and stability before coordinating the result with construction methods and applicable building codes. This sequence links conceptual planning to a buildable and safe structure.
When assessing a proposed structure, engineers can examine whether its elements and foundations provide a continuous, stable response to applied forces. Analysis focuses on safety, stiffness, strength, and stability, while broader review considers durability, costs, and resilience. The resulting evaluation helps determine whether the structural arrangement meets its intended performance requirements.
Building Structures apply across homes, workplaces, bridges, and public facilities, but the engineering questions remain connected: how loads move through the system, how elements respond to forces, and whether the selected design is durable and efficient. The context changes the architectural and construction requirements, while the underlying analysis guides safe decisions.
Structural design balances more than immediate load resistance. Engineers also seek durability, controlled costs, efficiency, and resilience to changing environmental and societal needs. Integrating these goals with architecture, construction methods, and building codes helps produce facilities that remain useful and dependable over time, rather than satisfying safety considerations in isolation.
