Maintenance-based Design of Concrete Parking Structures
نویسنده
چکیده
The purpose of this study is to determine what type of preventative maintenance for a concrete parking structure will produce the maximum economic benefit. Existing models for concrete deterioration are analyzed for their accuracy in predicting the service lives of concrete structures and a model appropriate for concrete parking structures is selected. The selected model is modified to account for the unique microclimate that is created within a parking structure and used to create deterioration curves that quantify the fraction of a structure deteriorated at a given time. Several preventative maintenance programs that summarize current practice in the repair of concrete parking structures are created. The programs are analyzed using the selected concrete deterioration model and the method of preventative maintenance that maximizes the net present worth of a concrete parking structure is identified.

In this research, Performance-Based Plastic Design (PBPD) method has been modified according to the proposed method for considering Soil–Structure Interaction (SSI) effects. In the proposed modified method, based on the existing relationships and in order to maintain the simplicity of the PBPD design method, two important parameters have been modified in the PBPD design method. These two parame...

Calibration of Load and Resistance Factors for Reinforced Concrete
Current approach for designing of reinforced concrete members is based on the load and resistance factor. However the load and resistance parameters are random variables, the constant values have been designated for them in the designing procedure. Assuming these factors as the constants, will be led to the unsafe and uneconomical designs. Safe designing of structures requires appropriate recog...
