Each file contains the time vector [sec] and the ground acceleration vector [m/sec/sec]. The first row of the file is time and second is acceleration. The last point in each record has been set to time=600, acceleration = 0 in order to take enough margin. Following files are required. elcentro.mat - El Centro earthquake record (e). hachinhe.mat - Hachinohe earthquake record (h). kobe.mat - Kobe earthquake record (k). northrdg.mat - Northridge earthquake record (n). ------------------------------- --- 2. Important Parameters --- ------------------------------- No_bld: Target Building 3: LA 3 Story Building 9: LA 9 Story Building 20: LA 20 Story Building Idx_linear (1: Linear, Otherwise: Nonlinear) Idx_Band (1: Banded Solver, Others: Symmetrical Solver) -------------------------- --- 3. GETTING STARTED --- -------------------------- 3.1 Required Software - MATLAB 5.2 or greater (must be allocated ~32 MB of memory) - MATLAB SIMULINK Toolbox - MATLAB Control Toolbox 3.2 The Benchmark Control Problem The essence of the benchmark control problem lies here. As a Designer/ Researcher it is your task to define a candidate control strategy. This is done in the following steps. 1) Select a structure that you wish to control from the three provided within this study: the 3-story LA SAC building; the 9-story LA SAC building; or the 20-story LA SAC building. Indicate your choice by defining , , or . 2) Define the number and location (as well as local dof) of the structural responses required by your control strategy for evaluation, sensor and connectivity purposes in the file inout_#.m. Include models for your sensors. See section 5.2 for further information. 3) Define the number and location (as well as local dof) of the control forces to be used in your control strategy also in the file inout_#.m. 4) Define your controller, either passive, semi-active or active, in the file ctrlr_#.m. 5) Modify the 'Sensor' and 'Controller' blocks in the SIMULINK model Sim_NLBM.mdl to accommodate your control strategy. You are now ready to execute the simulations. 3.3 Executing the Simulations There are two ways to execute the simulations. One is to use the 'Run_NLBM.m' program and the other is to run a particular simulation directly from the command line and Simulation menu in the SIMULINK window. <> 1) Type at the MATLAB prompt. This command runs the file 'Run_NLBM.m' which execute simulations. Note: The program is designed to execute the simulation in which El Centro earthquake is first used. Sim_NLBM must be set up initially with the Ground Accelerations port of El Centro connected. <> 1) Type , , or at the MATLAB prompt to indicate which target building you wish to simulate. 2) Type at the MATLAB prompt. This command runs the file 'Bld_NLBM.m' which makes structural data and set parameters to the SIMULINK model. 3) Type to open the SIMULINK simulator. 4) Select input earthquake and define the proper stop time in simulation parameters (100 sec for El Centro, Hachinohe and Northridge, 180 sec for Kobe). 5) Type , , or at the MATLAB prompt to indicate which level of the earthquake you wish to simulate. 6) Select 'Start' in the SIMULINK Simulation. 3.4 Changing the Integration Time Step The time step for integration can be set to any value between 0.001 sec and 0.01 sec. This should correspond to the sampling time of the digitally implemented controller for active and semi-active strategies, and should be set to the maximum (0.01 sec) for passive strategies, for optimal simulation speed. The integration time step can be changed by changing the parameter 'dt_cal' in the data file 'struct#.m' The default time step is 0.01 sec. -------------------------- --- 4. POST PROCESSING --- -------------------------- Once the simulation has been performed for each of the earthquakes and the data is stored, the sample control system can be evaluated using the MATLAB function 'EvalNLBM.m'. This program is provided as a template for calculating the evaluation criteria. Modifications to this program may be necessary for different choices of control devices, configurations, and algorithms. 4.1 MEM_DAMAGE DATA FILE In addition to the output data specified by each participant (in the in_output.m file) to determine the evaluation criteria for the building responses, control devices and control strategy, data is automatically saved to the data file Mem_damage.out for determination of the building damage evaluation criteria. This file contains the variable Mem_damage and the following information: Phi_j - curvature at the end of the j-th connection divided by the yeild curvature: Mem_damage(j,5) Phi_j_norm - normed curvature at the end of the j-th connection divided by the yeild curvature: Mem_damage(j,6) dEj - dissipated energy at the j-th connection divided by the product of the yeild moment and yeild curvature: Mem_damage(j,7) Nc - number of damaged connections: as indicated by a actual to yeild curvature ratio of greater than 1.0 (e.g. Mem_damage(:,5)>1.0) ---------------- --- 5. Notes --- ---------------- 5.1 UNITS In the model, the units of the inputs and outputs of the structure are: Inputs: Ground Acceleration [m/sec^2] Control Forces [N] Responses: Relative Displacements [m] Relative Velocities [m/sec] Absolute Accelerations [m/sec^2] 5.2 SENSORS The designer should describe and model the sensors employed in each proposed control system, including the sensitivity of the device. In the simulation 'Sim_NLBM.mdl', a {Sensors} block is included, which converts the physical measurements (e.g. accelerations) to sensor outputs (voltages) before any feedback signals pass through the 'Saturation' and {Quantizer} blocks (simulating the effects of the A/D converter). For the sample control design, feedback is provided by accelerometers with a sensitivity of 1g = 10V where 1g = 9.81 m/sec^2. It is left to the researcher/designer to define the units for his/her sensor model(s) and control device model(s) and ensure that they are consistent with those of the structure. 5.3 Structural Data File Structural data file defines structural data for simulation. In the benchmark study the LA 3-, 9-, and 20-story building structures are already defined. Researchers/Designers can change calculation parameters in this file. The dt_cal and dt_out and output options can also be changed within the constraints specified in Section 3.4 and in the paper. 5.4 User Defined Input/Output data file In the user defined file, such as 'inout_#.m' researchers/designers should define the input-ports and out-ports from the Newmark-beta block. Researchers must define the location (node number), direction (horizontal, vertical or rotational) and the response (absolute acceleration, relative velcoity or relative displacement). The variable of 'obs' defines the location, direction and response of ye, used for the evaluation. The variable of 'snr' defines the location, direction and response of ym, which is for sensors. Note that only absolute acceleration responses are available for feedback measurement in the nonlinear benchmark study. The variable 'cps' defines the location, direction and responses of yc, which is for connection points. The variable of 'cps' defines the location of control forces, which are calculated and generated in the control block. Also note that for the sample control strategy, the output data is specified to produce a vector of evaluation responses for the displacement, velocity and acceleration of each level (and not all displacements, all velocities, all accelerations). This can be changed for different proposed control stategies if desired, but calculation of the evaluation criteria for the sample control strategy is based on this format. +----------------------+ | |---> ye ag --->| | | |---> ym f --->| | | |---> yc +----------------------+ obs: Defines Observations for Evaluations (ye) snr: Defines Sensor Positions for Acquisition (ym) cps: Defines Connection Positions of Passive Devices (yc) cf : Defines Location of Control Forces (f) 5.5 User Defined Controller data file The 'ctrlr_#' data file defines controller parameters which are required in the SIMULINK model during the simulation. Data for Sensors (for Structure: acceleration) Data for Control Signals Researcher/designers should define each algorithm and device in this file. --------------------------------------------------------- ********************************************************* Questions can be directed to Prof. B.F.
