Building Summary
Building Summaryaileencv
Ìý
The 9-story building structure passed the initial nonlinear static analysis but failed the life safety standards on the first story beam. In the linear dynamic analysis, the columns of the first three stories and beams of the 7th and 8th stories failed. To fix this, the columns were redesigned with larger dimensions and reinforcement, while the beams at the top were redesigned with less reinforcement. These changes increased the column stiffness and reduced top beam stiffness, allowing the building to pass the linear dynamic analysis.555 timer-digital-clock

This document discusses the 555 timer integrated circuit and its use in building a digital clock circuit. It provides details on the 555 timer pins and its three operating modes: astable, monostable, and bistable. It then describes a digital clock circuit built using a 555 timer chip that displays time on 7-segment displays and can be set using buttons. Links are provided for additional information on 555 timer clocks.Melissa Lorenzo Resume

The document summarizes the key differences between light microscopes and electron microscopes. Light microscopes have a resolving power of about half the wavelength of visible light, limiting magnification to around 1500x. Electron microscopes use short wavelength electrons, allowing much higher resolving power and magnification over 500,000x. There are two main types: transmission electron microscopes (TEM) that pass electrons through thin samples, and scanning electron microscopes (SEM) that detect electrons reflected from surfaces to generate 3D images. TEMs require harsh chemical fixation of cells that can introduce artifacts.Digital clock

The presentation introduces digital clocks, including their history, components, implementation, uses, and future plans. It discusses how the first digital watches were invented in the 1880s and the first digital alarm clock was patented in 1956. The presentation implements a digital clock circuit in Multisim using ICs like 74LS47, 74LS90, 74HC32, and other components like function generators, push buttons, and 7-segment displays. Digital clocks are now commonly used in devices like cars, radios, TVs, and computers to display time accurately and easily readably compared to analog clocks. Future plans include adding time setting, on/off, date, and alarm functions.

Structural health monitoring uses sensors and data collection techniques to monitor structures for damage or changes over time. This improves safety, reliability and reduces costs. The document discusses using P3HT, a conductive polymer, for sensors as it displays electro-chemical sensing abilities. SHM involves identifying critical damage types, data acquisition from sensors, signal processing, and statistical modeling to correlate responses to damage types.Advanced Composites Final Paper

This document summarizes the final project for a 9-story building located in California designed to seismic standards. It includes pushover curves analyzing the building's response to lateral loads, linear dynamic analysis per FEMA-356, and a sensitivity study exploring the effects of increased mass, reduced member stiffness, and scaled ground motions. The analysis required reinforcing the first story columns more but less for 7th story beams. The design proved highly sensitive to changes and will require closer inspection.Subspace Identification

This document discusses sub-space system identification. It begins with an introduction to state space representation and the difference between deterministic and stochastic systems. It then outlines the procedure for sub-space identification, which involves generating block Hankel matrices and extracting system parameters. As a case study, it examines using sub-space identification to calibrate a finite element model of a 17th century bridge by determining its natural frequencies and mode shapes from ambient vibration data. This led to an updated model with better accuracy in predicting the bridge's earthquake response.Fiber Optics Presentation

Fiber optic sensors have four potential functions in structural health monitoring: monitoring external manufacturing process parameters, serving as embedded sensors for non-destructive evaluation, functioning as a data-link network to support other SHM systems, and complementing performance monitoring and control systems. Fiber optic sensors have advantages over conventional electronic sensors in that they are made of silica-based materials, enable multiplexing, and have a lower cost. They can provide distributed sensing along structures like buildings to monitor temperature. Fiber Bragg grating sensors embedded in concrete have been used to measure strain on the Confederation Bridge in Canada.More Related Content
