Abstract: Despite advances in the computer analysis of frame buildings for lateral loads, there remains a need for simple models that provide accurate estimates of response. The concept of lateral stiffness is reviewed, and it is ...

Abstract: The seismic behavior of reinforced concrete (RC) frames with hinging columns, also known as strong‐beam–weak‐column (SBWC) frames, is studied from earthquake‐simulation test results of two small‐scale models. The models ...

Abstract: Unlike the use of bonded reinforcement to anchor a masonry wall to its foundation, the use of unbonded posttensioning may result in a controlled rocking response of the wall. Considering that conventional analysis techniques ...

Abstract: The prevalence of fatigue cracking in steel bridge girders due to out-of-plane web distortion motivates development of procedures to evaluate the effects of distortional fatigue. In a previous study sponsored by the Minnesota ...

Abstract: Nonlinear finite-element models were developed, verified, and used to simulate the measured response of twelve 3.54 m (11.6 ft) tall posttensioned masonry walls with

Abstract: Unbonded post-tensioned (UPT) tendons have been used in structural masonry walls to enhance the self-centering capability of the walls. However, the lateral displacement capacity of masonry walls with UPT tendons can be ...

Abstract: Each year a large number of concrete bridges are subjected to impact by overheight vehicles or vehicles carrying overheight objects. Most bridge owners in the United States are concerned with the increasing trend of bridges ...

Abstract: A conceptual model of the response of slender, posttensioned masonry walls to uniformly distributed, transverse loading is introduced and verified through an experimental program. To validate the model, 12 simply supported ...
