RISApproximate Method for Estimating Extreme Value Responses of Nonlinear Stochastic Dynamic Systems
Publisher: American Society of Civil Engineers
Abstract: This paper proposes an approximate method for estimating the extreme value responses of nonlinear dynamic systems to random excitations. The method focuses on the mean zero responses with the unimodal and symmetrical ...
Behavior and Design of Cold-Formed Steel Web-Stiffened Channels under Concentrated Bearing Loads
Publisher: ASCE
Abstract: This study focused on the web crippling and design of web-stiffened channel sections made of cold-formed steel (CFS). CFS web-stiffened channels are expected to have higher buckling loads under compression and bending ...
Experimental and Numerical Investigation on the Anchorage Zone of Prestressed UHPC Box-Girder Bridge
Publisher: ASCE
Abstract: The structural behavior of the anchorage zone is a key issue in prestressed ultra-high performance concrete (UHPC) box-girder bridges. This study investigates the mechanical behavior of a diaphragm–blister integrated ...
Durability of Soft Soil Treated with Soda Residue and Ground Granulated Blast Furnace Slag in a Soaking Environment
Publisher: ASCE
Abstract: This study investigates the effect of soaking conditions on the durability of soft soil treated with soda residue and ground granulated blast furnace slag. Specimens were cured for up to 60 days and soaked in solutions ...
Experimental and Numerical Evaluation of a Welded Demountable Shear Connector through Horizontal Pushout Tests
Publisher: ASCE
Abstract: A novel welded demountable shear connector for sustainable steel-concrete composite structures is proposed. The proposed connector consists of a grout-filled steel tube bolted to a compatible partially threaded stud, which ...
Mechanical Performance of Steel-Concrete Composite Beams Subjected to a Hogging Moment
Publisher: American Society of Civil Engineers
Abstract: Limited experimental results have been reported in the literature on the fatigue and ultimate static loading behavior of composite beams subjected to negative bending moment. This paper examines experimentally the behavior ...
Hazardous Area Risk-Based Evacuation Simulation and Analysis of Building Construction Sites
Publisher: ASCE
Abstract: Building construction sites are highly complex and uncertain, and frequent incidents of dangerous events can easily lead to casualties. Thus, both risk assessment and evacuation analysis are fundamental to safety management. ...
Steel-Yielding Demountable Shear Connector for Composite Floors with Precast Hollow-Core Slab Units
Publisher: American Society of Civil Engineers
Abstract: A demountable shear connector for use in composite floors with precast hollow-core slab units is proposed. The proposed shear connector consists of a steel square hollow tube welded on a steel plate that is bolted on the ...
Standard Pushout Tests and Design Rules for a Bolted–Welded Hybrid Demountable Shear Connector
Publisher: ASCE
Abstract: A bolted–welded hybrid demountable shear connector for use in deconstructable steel–concrete composite buildings and bridges was proposed. The hybrid connector consisted of a partially threaded stud, which was welded on ...
