Institute of Museum and Library Services The new provisions are based on the use of a displacement‐based design methodology, which is a significant departure from prior codes.
The inelastic deformations for a CIDH shaft/column occur below grade; therefore, the overall lateral load behavior of the system is influenced by the interaction between the shaft and the surrounding soil, commonly modeled using p-y curves. The equipment includes shakers for exciting structural systems, numerous sensors for monitoring accelerations and deformations within the excited structure (e.g., accelerometers, strain gauges), and real time data acqui... We begin by reviewing SFSI effects from both demand and capacity perspectives.
In high seismic regions, post-tensioned (PT) slab-column frames are commonly used to support gravity loads in conjunction with a lateral-force resisting system (LFRS; e.g., a core wall).
The same is not true for wind design, which has historically been limited to the realm of linear elastic design. SNAC is a discovery service for persons, families, and organizations found within archival collections at cultural heritage institutions.
We examine several aspects such as reliability, latency and data integrity... Splices in reinforced concrete columns of older buildings were commonly designed as compression lap splices, which are typically only 20 to 24 bar diameters (db) long and enclosed within light transverse reinforcement. The ACI 318-99 provisions apply to both slender and stout walls, and walls with openings. All rights reserved. The numerical algorithm for subspace state space system identification is employed to identify the structural frequencies, damping ratios, and mode shapes correspo... Analytical and experimental studies were undertaken to assess and improve modeling techniques for capturing the nonlinear behavior of flat plate systems using results from shake table tests of two, approximately one-third scale, twostory reinforced concrete and post-tensioned concrete slab-column frames. View. Results of lateral-load testing of isolated post-tensioned slab-column connections subjected to quasi-static loading have consistently shown that the ACI 318-05 1 provisions overestimate the nominal stresses in unbonded tendons, suggesting that the current provisions overestimate the available flexural strength for post-tensioned slabs.
